[0001] The present application claims the priority benefit of U.S. Provisional ApplicationNo. 63 / 636,506, filed April 19, 2024, which is hereby incorporated by reference in its entirety.FIELD OF THE DISCLOSURE

[0002] The disclosure relates to biofertilizers and diluents extracted from plants, yeast, insects, crustaceans or algae.BACKGROUND OF THE DISCLOSURE

[0003] Microbial-based fertilizers or biostimulants are produced through fermentation processes to generate single or multi-strain products that can be applied in conjunction with standard farmer practices. The focus of fermentation is to achieve a total cell and / or spore density that provides the best plant responses such as increase biomass, fruit quality and / or yield, growth disease and / or chemical over application resistance. Traditionally the product of the fermentation process is applied directly with minimal downstream processing at a given rate based on trials and experimentation.

[0004] However, a need exists for new microbial-based fertilizer products.BRIEF SUMMARY

[0125] In order to further define this disclosure, the following terms and definitions are provided.

[0126] The singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. The terms "a" (or "an"), as well as the terms "one or more," and "at least one" can be used interchangeably herein. In certain aspects, the term "a" or "an" means "single." In other aspects, the term "a" or "an" includes "two or more" or "multiple."

[0127] The term "about" is used herein to mean about, roughly, around, or in the regions of. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term "about" is used herein to modify a numerical value above and below the stated value by a variance of 10 percent, up or down (higher or lower).

[0128] The term "and / or" where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. Thus, the term "and / or" as used in a phrase such as "A and / or B" herein is intended to include "A and B," "A or B," "A" (alone), and "B" (alone). Likewise, the term "and / or" as used in a phrase such as "A, B, and / or C" is intended to encompass each of the following aspects: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).

[0129] Throughout this application, various embodiments of this invention can be presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexiblelimitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range, such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 2, from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 3, from 2 to 4, from 2 to 5, from 2 to 6, from 3 to 4, from 3 to 5, from 3 to 6, etc., as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range. Furthermore, a recited range should be considered to include the end points of the range. For example, "between about 15 and about 50" should be interpreted to include about 15, about 50, and subranges between as described above.

[0130] The terms "comprises," "comprising," "includes," "including," "having," and their conjugates as used herein are interchangeable and mean "including but not limited to." It is understood that wherever aspects are described herein with the language "comprising," otherwise analogous aspects described in terms of "consisting of' and / or "consisting essentially of' are also provided.

[0131] The term "consisting of as used herein means including and limited to.

[0132] The term "consisting essentially of as used herein means the specified material of a composition, or the specified steps of a method, and those additional materials or steps that do not materially affect the basic characteristics of the material or method.

[0133] As used herein, the term "effective amount" in terms of a biofertilizer will depend upon a variety of factors, including, for example, percent viability of cells in the biofertilizer, concentration of cells in the biofertilizer, the levels of nutrients, including ammonia and carbon sources (e.g., PHB), and whether the biofertilizer is in the form of a liquid cell suspension or comprises a solid biomass component, such as soils, plant materials, or inert materials. A person of ordinary skill in the art will be able to determine an effective amount taking into account these variables. For purposes of the instant disclosure, an effective amount of a biofertilizer means an amount of the biofertilizer that is sufficient to result in an enhanced property or characteristic of a soil microbiome and / or a crop or plant that is statistically greater than the same property or characteristic in the absence of the biofertilizer, such as, for example, increased crop yield, increased fruit or vegetable yield or root storage mass, increased carbon and / or nitrogen availability in the microbiome. In some aspects, the property or characteristic e.g., crop or plant yield or yield quality) enhanced by the biofertilizer is observed with at least a 5%, or at least a6%, or 7%, or 8%, or 9%, or 10%, or 25%, or 50%, or 75%, or 100%, or 200%, or 300%, or 400%, or 500%, or 1000%, or 1250%, or 1500%, or 2000%, or more increase over the same property or characteristic established in the absence of the biofertilizer.

[0134] As used herein, the term "microbiome" refers to the collection of all microorganisms living in a particular environment, including in the soil surrounding and / or interacting with the root of a plant.

[0135] As used herein, the term "biofertilizer" refers to a preparation containing living cells or latent cells of microorganisms that help plants (e.g., crop plants) grow. The term also refers to a preparation containing living cells or latent cells of microorganisms that help to feed and / or enhance the soil microbiome. The term also refers to a preparation containing living cells or latent cells of microorganisms that produce chemicals (including but not limited to nitrate, ammonia, phosphorus) to directly or indirectly provide nutrition to plants (e.g., crop plants), or to directly or indirectly signal plant or microbial pathways to the benefit of the plant (e.g. crop plants), in the soil, soilless substrate, or other growth medium. In some aspects, the biofertilizer can be a preparation containing living cells or latent cells of microorganisms, or having enhanced accumulation of microbial intracellular storage compound (MISC), or a combination thereof. In some aspects, the MISC accumulated by the microorganism comprises a polyhydroxyalkanoate (PHA), a polyphosphate (PolyP), a lipid, or a combination thereof. In some aspects, the MISC is a PHA. In some aspects, the PHA is polyhydroxybutyrate (PHB), poly-3 -hydroxybutyrate (P3HB), poly-4-hydroxybutyrate (P4HB), polyhydroxyhexanoate (PHH), polyhydroxyoctanoate (PHO), polyhydroxyvalerate (PHV), or a copolymer thereof. In one aspect, the PHA is PHB.

[0136] As used herein, the term "nitrogenase" refers to an enzyme that is produced by certain specialized bacteria called nitrogen-fixing bacteria, such as cyanobacteria and Xanthobacter (e.g., X. autotrophicus), which are responsible for reducing atmospheric nitrogen (N2) to ammonia (NH3) as part of the nitrogen cycle.

[0137] As used herein, the term "stable" or "stability" refers to the viability of the microorganisms in biofertilizers. Biofertilizers comprise living microorganisms, unlike chemical fertilizers. Biofertilizers themselves can comprise the source of nutrients, and / or can help the crops or plants in accessing the nutrient available in its surrounding environment. The viability of the microorganisms during production, formulation, storage, transportation, distribution and field application is directly related to theperformance and potentials of a biofertilizer. A range of commercial biofertilizer formulation strategies can be applied to ensure maximum viability of the microorganisms used in such formulations. These strategies include: (i) optimization of biofertilizer formulation, (ii) application of thermo-tolerant / drought-tolerant / genetically modified strains and, (iii) application of liquid biofertilizer. For convenience of application, a carrier material can be used as a vehicle for the microorganisms to be used as biofertilizer. Moreover, such materials can have a role in maintaining the viability (shelflife) of the microorganisms prior to its release into the field as well as they also provide a suitable microenvironment for rapid growth of the organisms upon their release. A carrier can be a material, such as peat, vermiculite, lignite powder, clay, talc, rice bran, seed, rock phosphate pellet, charcoal, soil, paddy straw compost, wheat bran or a mixture of such materials. In common practice, for a better shelf-life of a biofertilizer formulation, a carrier or a mixture of carrier materials can be selected based on the viability of the microorganisms mixed with them. Similarly, pre-sterilization of the carrier material and its enrichment with nutrients can be another strategy for improving the shelf-life by allowing the microorganism to maintain and grow in a non-competitive microenvironment. Sucrose, maltose, trehalose, molasses, glucose, and / or glycerol can be supplementary nutrients or cell protectants commonly used with a carrier material to ensure maximum cell viability and extended shelf-life. Liquid biofertilizer formulations can be considered as one potential strategy for improving the shelf-life of biofertilizer. Unlike solid carrier based biofertilizers, liquid formulations allow the manufacturer to include sufficient amount of nutrients, cell protectant, and inducers responsible for cell / spore / cyst formation to ensure prolonged shelf-life. The shelf-life of common solid carrier based biofertilizers can be around six months; however, it could be as high as two years for a liquid formulation. Further, solid carrier based biofertilizers can be less thermo-tolerant, whereas liquid formulations can tolerate the temperature as high as 55°C. Hence, improved shelf-life can be achieved formulating biofertilizers into liquid formulations.

[0138] The term "derived from" as used herein refers to a component that is isolated from or made using a plant (e.g., an extract or tea), yeast (e.g. spent brewing yeast), insect (e.g., honey), or algae. For example, a diluent that is derived from a plant can include a tea obtained from plant biomass.

[0139] The term "growth disease" as used herein refers to any disease or condition that adversely affects the normal growth of a plant. For example, growth diseases may include a fungal disease (e.g., powdery mildew, downy mildew, or blight) or tip burn.

[0140] The term "Chemical Over Application" as used herein refers to over application of fertilizer, pesticides, or other chemicals used during agriculture practices which may lead to negative consequences. For example, over application of fertilizers may lead to decreased soil health and plant fertility (e.g., by depletion of essential soil nutrients and minerals or increased salt content).

[0141] The term "efficacy of a microorganism" as used herein refers to the ability of microorganism to produce a desired biological effect in a plant (e.g., increased nitrogen utilization efficiency, increased biomass, increased fruit quality, increased growth rate, increased lateral root density, increased yield, increased resistance to growth disease, or increased resistance to chemical overapplication).

[0142] The term "v / v" or "% v / v" as used herein refers to the concentration of one liquid in another liquid obtained by comparing the relative volumes of one liquid and the other liquid. For example, a composition comprising 80% v / v diluent contains 80 mL of diluent per 100 mL of total solution (e.g., a composition disclosed herein).

[0143] The term "w / w" or "% w / w" as used herein refers to proportions by weight, and means the ratio of the weight of one substance (e.g., a dry formulated diluent) in a composition to the total weight of the composition, or the weight of one substance in the composition to the weight of another substance of the composition. For example, reference to a composition that comprises 80% w / w diluent means that 80% of the composition's weight is composed of diluent (e.g., such a composition having a weight of 100 mg would contain 80 mg of diluent) and the remainder of the weight of the composition (e.g., 20 mg in the example) is composed of other ingredients (e.g., a microorganism).

[0144] As used herein, "spray drying" refers to processes that produce dry powders from a liquid or slurry. "Spray dried," when referring to a substance, refers to a substance that has undergone the spray drying process.

[0145] As used herein, "steeping" refers to soaking in a liquid to soften, cleanse or extract some constituent.

[0146] As used herein, "homogenizing" refers to intensive mixing to obtain a soluble suspension or emulsion. Homogenization may be performed to break down the biomass(e.g., a plant, yeast, insect, crustacean or algae) into smaller sizes. This can be achieved by forcing the biomass (e.g., a plant, yeast, insect, crustacean or algae) through small holes at high pressure.

[0147] As used herein, "diluent" refers to a substance used for dilution (e.g., for diluting a microorganism). In some aspects, the diluent is derived from a plant (e.g., the seeds, the leaves, the roots, the shoots, the flower, or the fruit of the plant, or the entire plant), yeast, insect, crustacean or algae.Compositions and / or Formulations

[0160] Diluent or microorganisms (generally liquid, but also semi-solid or solid) may be dried, dehydrated or desiccated using a variety of methods. In some examples, a liquid sample may be left open so that moisture from the sample is evaporated into the air. This may be called air drying. In some examples, a gas stream (e.g., air) may apply heat to the sample by convection and moisture / vapor is removed as humidity. In some aspects, vacuum drying, where heat is supplied to the sample by conduction, radiation, or microwaves, vapor is produced and carried away by a vacuum system, may be used. In some aspects, drum drying, where a surface supplies heat to the sample, vapor is produced and carried away by an aspirator, may be used. In some aspects, a dried sample may be produced by draining (e.g., centrifugation to mechanically extract a solvent).

Minimal CPUs required with biofertilizer for lettuce

[0430] The purpose of this experiment was to observe a dose response in lettuce when applying a biofertilizer comprising a microorganism (e.g., Xanthobacter autotrophicus with high Polyhydroxybutyrate (PHB)) with an optimal application method. This experiment determined a minimal threshold at which the biofertilizer confers a benefit to lettuce, and the effect that increasing the amount of the biofertilizer has on plant growth.

[0431] Treatments were included to measure an optimal application rate with and without the addition of Diluent #1.

[0432] The objective of this experiment was to observe a dose response in lettuce plants. Total CFUs ranged from 1.0E9 to 4.0E10 with the intent of finding a lower threshold at which the biofertilizer could be dosed to provide a significant benefit.

[0433] Furthermore, there were treatments diluted lOx in diluent #1. This added an additional element to the optimal application rate as it was determined if the threshold number of CFUs for observing a replacement effect can be further lowered when the product is supplemented with Diluent #1.

[0434] Experimental Design

[0435] 120 plants were used, with 10 treatments applied to 6 plants in duplicate, as described in Table 1. Microorganisms were applied by either root dipping or pipette additions.

[0436] For root dipping, the following steps were performed: a) 12 seedlings were taken up at a time and placed in weigh-boat, or some other small container.b) Microbial product was diluted aseptically to desired density in water, in separate sterile 50 mL tube. Product was mixed / vortexed while diluting. Total volume should be equal to number of plants x3 (in mL).(c) 3 mL of dilute microbial product was added per seedling to weigh boat.(d) The seedling and microbial product soaked and sat for 5 minutes.(e) The seedlings were transplanted as normal in randomized pattern into pots.

[0437] For pipetting, the following steps were performed:(a) Desired application volume and density was determined as part of experimental design.(b) Microbial product was aseptically diluted to desired density in water, in separate sterile 50 mL tube. Product was mixed / vortexed while diluting. Total volume should be equal to number of plants x3 (in mL).(c) Sealed container of microbial product was transferred to grow box.(d) Desired volume was pipetted to the base of each plant, being sure to mix diluted sample throughout. Directly touching plant / dirt with pipette tip was avoided when going between diluted mixture and application. Note: excessive watering of pots was avoided after dosing plants with microbial product.Table 1 - Treatment Groups

[0438] Biofertilizer / Diluent #1 was dosed as described in Table 2:Table 2 - Biofertilizer / Diluent #1 dosage

[0439] At the beginning of the experiment, a 1 : 10 dilution of the biofertilizer was made by mixing 2 mL of the biofertilizer into 18 mL of Diluent #1. This was kept sterile in a refrigerator through the entirety of the experiment. The Diluent # 1 was steeped at 55°C and made at a concentration of 21.13 g / L.

[0440] Nitrogen Fertilizer Treatments were dosed at 50 mL to the base of each plant. Calculations for UAN-32 additions to 100% Hoagland's solution without N are listed in Table 3.

[0441] Tables 4-7 describe the designs for Replacement Effect (Table 4), Replacement and Boosting Effect (Table 5), Application Rate Comparison (Table 6), and Diluent optimization - final cell density (Table 7).Table 3 - Fertilizer TreatmentTable 4 - Replacement EffectTable 5 - Replacement and Boosting EffectTable 6 - Application Rate ComparisonTable 7 - Diluent optimization - final cell density

[0442] Starting on day 5, weekly doses of 50 mL of 100% Hoagland's Solution without N were provided to supplement other nutrients.

[0443] Diluent #1 Preparation

[0444] Diluent #1 was prepared as follows:

[0445] In a cloth bag, 20-110g of dry alfalfa pellets were mixed with 1 L of 4°- 95°C water and steeped for 0.5-18 hrs. The resulting extract (4°C-70°C) was processed through 0.8 / 0.45 pm filter to remove suspended solids prior to sterile filtration though a 0.22 pm pore filter. Alternatively, steepage was autoclaved for 20 min at 121 °C 15 psi. The steepage was then stored at 4°-23°C for use at the desired mixing ratio.

[0446] At time of harvest, the following was collected:1) Aboveground imaging,2) Aboveground Fresh and Dry Weight,3) Belowground Dry Weight,4) Root imaging (if necessary), and5) WARD Nutritional data: Aboveground, Belowground & Soil.

[0447] Results.

[0448] Nutrient data showed an increase in nitrogen utilization efficiency (NUE) in the group receiving the most concentrated biofertilizer in Diluent # 1. See Figure 1A. An increase in NUE suggested either an increased efficiency of nitrogen uptake, or (more likely in this case) a greater input of nitrogen into the system from nitrogen fixation.

[0449] Aboveground yields showed that the biofertilizer and the biofertilizer in Diluent #1 both show significant nitrogen replacement effects. Diluting with Diluent #1 lowers the threshold of CFUs at which a significant replacement effect was observed. Just looking at the aboveground fresh-weight, a significant replacement effect was observed when a total of 4.0E8 CFUs were delivered with the biofertilizer in Diluent #1, whereas the same level of replacement required 1.0E10 CFUs when the biofertilizer was undiluted. See Figures 1B-1C. Belowground dry weight showed a very different pattern, especially in the biofertilizer undiluted treatment group. However, belowground dry weight was not as strong of an indicator of nitrogen replacement effect. See Figure ID.

[0450] The purpose of this experiment was to observe a dose response in lettuce when applying the biofertilizer with an optimal application method (starter dose, weekly application of product). This experiment looked to both determine a minimal threshold at which the biofertilizer confers a benefit to lettuce, and test whether increasing the amount of the biofertilizer has a positive effect on plant growth.

[0451] Additional treatment groups were included to measure an optimal application rate with and without the lOx dilution into Diluent #1.

[0452] Total CFUs ranged from 1.0E9 to 4.0E10 for the undiluted biofertilizer groups and 1.0E8 to 4.0E9 for the Diluent #1 groups (lOx dilution). Application volume was kept consistent throughout the study (total of 1 mL per plant per application).

[0453] Aboveground yield data showed a strong dose response for both biofertilizer and Biofertilizer / Diluent #1 treatment groups: as application increased, so too did yield. Treatments prepared in Diluent #1 showed a decreased threshold of CFUs at which significant nitrogen replacement occurred.

[0454] Treatments prepared in Diluent #1 had a lower threshold of CFUs at which significant nitrogen replacement occurred:>4.0E+8 CFUs in D#1 conferred significant N-replacement effect>1.0E+10 CFUs undiluted conferred significant N-replacement effect

[0455] The treatment group with the highest application rate in Diluent #1 had the highest nitrogen utilization efficiency, which suggested increased rates of nitrogen fixation and / or the ability to uptake nitrogen more efficiently.

[0456] These results suggest that 1.0E10 CFUs was an acceptable application rate for the biofertilizer undiluted. This experiment confirmed the optimal application rate of thebiofertilizer undiluted: 1.0E+10 CFUs for a 4 week lettuce trial. This is equivalent to 20 oz / acre of product and was estimated to replace about 10 pounds N / acre.

[0457] Surprisingly, the experiment showed that 4.0E+8 CFUs in D#1 also conferred significant N-replacement effect. This allows for a reduction in the amount of CFUs needed to confer a yield response. For example, comparing 1) lelO CFU vs. 2) 4e8 CFUs in D#1 represents an unexpected 25 fold reduction in CFUs needed to achieve a yield response.

[0458] Additionally, Biofertilizer and Biofertilizer + DI diluent showed higher % yield increase relative to 80% GSP, in addition to increased Nitrogen Use Efficiency (NUE) relative to both 80% GSP and 100% GSP. See FIGs. 27A-27B. Similar results were seen when 100% GSP was boosted with Biofertilizer or Biofertilizer + DI, while DI alone did not show higher yield or NUE. See FIGs. 28A-28B. Replacement with 8 ounces of Biofertilizer + DI saw minor improvements in yield and NUE relative to 2 ounces of Biofertilizer + DI, while no improvement was seen in 2 ounces of Biofertilizer alone compared to 8 ounces of Biofertilizer alone. See FIGs. 29A-29B. Finally, Biofertilizer + DI applied at 1E9 CFUs saw the most improved yield and NUE. See FIGs. 30A-30B.Example 2 - Diluent 1 dilution trial

[0459] The objective of this assay was to test the performance of the biofertilizer diluted in alfalfa tea. There were four treatments and the effects of adding the biofertilizer by volume as well as by CFU were compared. These four treatments of the biofertilizer and alfalfa tea were given to plants on top of a low nitrogen baseline of 80% GSP, and the plant response to these four treatments were compared to a low and high untreated nitrogen baseline.

[0460] Experimental Design

[0461] 72 plants were used, with 6 treatments for 6 plants in duplicate as described inTable 8. The treatments analyzed were:1) Low N UTC: 80% GSP,2) AK1 : 80% GSP+E 10 Biofertilizer / Dl by volume,3) AK2: 80% GSP+E 10 Biofertilizer / Dl by CFU,4) KI : 80% GSP+Biofertilizer at le+9,5) K2: 80% GSP+Biofertilizer at le+10, and6) High N UTC: 100% GSP.Table 8 - Treatment protocol

[0462] Plants dosed 50 mL of fertilizer blend: Hoagland's without nitrogen plus varying UAN-32 amounts. 80% GSP = 9.6 lb N / ac / application: 0.0260 mL UAN32 / pot / application. 100% GSP = 12 lb N / ac / application: 0.0326 mL UAN32 / pot / application. For low nitrogen, dosage was calculated for 64 plants (60 + 4 insurance). For high nitrogen, dosage was calculated for 13 plants (12 + 1 insurance). Each plant received 50 mL of Hoagland without nitrogen + UAN-32.

[0463] Fertilization was done weekly starting on days 1, 8, 15, 22 (after transplant).

[0464] Diluent 1 was prepared as follows:

[0465] In a cloth bag, 20-110g of dry alfalfa pellets were mixed with 1 L of 4°- 95°C water and steeped for 0.5-18 hrs. The resulting extract (4°C-70°C) was processed through 0.8 / 0.45 pm filter to remove suspended solids prior to sterile filtration though a 0.22 pm pore filter. Alternatively, steepage was autoclaved for 20 min at 121 °C 15 psi. The steepage was then stored at 4°-23°C for use at the desired mixing ratio.

[0466] Biofertilizer + DI treatment (KI) was prepared by:1) Pipet 0.05 mL HDB + 4.95 mL water to each seedling for day 0, and2) Pipet 0.023 mL HDB + 4.977 mL water to each seedling for day 7, 14, 21.

[0467] Biofertilizer (K2) was prepared by:1) Pipette 0.47 mL HDB + 4.53 mL water to each seedling for day 0, and2) Pipet 0.23 mL HDB + 4.77 mL water to each seedling for day 7, 14, 21.

[0468] 1 : 10 Biofertilizer / Dl treatment (AK1) was prepared by:1) Pipette 0.47 mL Biofertilizer / Alfalfa tea Mixed solution + 4.53 mL water to each seedling for day 0, and2) Pipet 0.23 mL Biofertilizer / Alfalfa tea Mixed solution + 4.77 mL water to each seedling for day 7, 14, 21.

[0469] 1 : 10 Biofertilizer / Dl treatment (AK2) was prepared by:1) Pipette 4.65 mL Biofertilizer / Dl Mixed solution + 0.35 mL water to each seedling, and2) Pipet 2.33 mL Biofertilizer / Dl Mixed solution + 2.67 mL water to each seedling for day 7, 14, 21.

[0470] Treatments were done weekly starting on day 0, 7, 14, 21(day of transplant).

[0471] Results

[0472] The purpose of this assay was to test the effects of diluting the biofertilizer in Diluent 1 1 : 10 and adding this mixture, in treatments that accounted for either volume or CFU, to plants. These Dl / biofertilizer treatments were compared to just biofertilizer treatments, and were given to plants on top of a low nitrogen baseline (80% GSP). There were also low and high controls of untreated 80% and 100% GSP plants.

[0473] The results of this assay show that the only treatment that was significantly different from the low nitrogen baseline was AK1. AK1 was the only treatment that significantly increased aboveground biomass compared to the low nitrogen control, and was insignificantly different from the high nitrogen control. See Figure 2.

[0474] There was no significant difference between the other treatments and the high nitrogen control, except between the low and the high nitrogen control.

[0475] In the case of AK1, at 80% GSP, the addition of Biofertilizer diluted in Diluent 1 for a total of 1E+09 CFUs was able to meet the nitrogen needs of the plants such that they were not significantly different from the high nitrogen control. Compared to the treatments AK2, where the same product was added based on CFU, we received a better result when we added biofertilizer diluted in Diluent 1 at 10 times lower the CFU.

[0476] The results of this assay indicate that the treatment that used Biofertilizer diluted in Diluent 1 for a total of 1E+09 CFUs delivered to the plant performed the best.

[0477] The tentative conclusion is that 1E+09 CFUs of Biofertilizer diluted in Diluent 1 is a treatment we should be targeting for further investigation.Example 3 - Plant response to Diluent treatments

[0478] The purpose of this assay was to test the plant response of Diluent #1, the biofertilizer, and the biofertilizer diluted in Diluent #1 in lettuce at a low and high nitrogen baseline. The low nitrogen baseline was 80% GSP, and the high nitrogen baseline was 100% GSP. The treatment of the biofertilizer diluted ten times in Diluent # 1 achieved a final concentration of 1E+09 CFU / mL.

[0479] The objective of this assay was to compare the effects of Diluent #1, the biofertilizer, and the biofertilizer diluted ten times in Diluent # 1 in lettuce when grown with a low and high nitrogen baseline.

[0480] It was hypothesized that the plant response would be greater in the treatments that had the biofertilizer and Diluent #1 than treatments with Diluent #1 alone.

[0481] Experimental Design

[0482] 96 plants were used, with 8 treatments for 6 plants in duplicate, as shown in Table9Table 9 - Experimental Design

[0483] 4° C Diluent #1 was prepared as follows:

[0484] In a cloth bag, 20-110g of dry alfalfa pellets were mixed with 1 L of 4°- 95°C water and steeped for 0.5-18 hrs. The resulting extract (4°C-70°C) was processed through 0.8 / 0.45 pm filter to remove suspended solids prior to sterile filtration though a 0.22 pm pore filter. Alternatively, steepage was autoclaved for 20 min at 121 °C 15 psi. The steepage was then stored at 4°-23°C for use at the desired mixing ratio.

[0485] Treatments were prepared as described in Table 10.Table 10 - Treatment protocol

[0486] N Fertilization was done weekly starting on day 0, 7, 14, 21 (day of transplant).Biofertilizer treatment and Diluent #1 was done weekly starting on day 1, 8, 15, 22 (day of transplant). N-Free Fertilization was done weekly starting on day 3, 10, 17, 24(day of transplant). See Table 11.Table 11 - Treatment Protocol

[0487] Results

[0488] The purpose of this experiment was to test the effect of 4°C Diluent #1, the biofertilizer, and the biofertilizer diluted ten times in Diluent #1 in lettuce at 80% and 100% GSP. In the low nitrogen baseline plants, all treatments were significantly different from the UTC. Though there was no statistically significant difference between the treatments, the AK1 treatment with the biofertilizer diluted in Diluent # 1 had the greatest fresh aboveground biomass. In the high nitrogen baseline plants, there was no statistical significance between the UTC and the three treatments. There was slight significance between the A2 and K2 treatments, and the AK2 and K2 treatments were both trending up from the UTC.

[0489] None of the treatments in the low nitrogen group were able to meet the high nitrogen group, but all were trending higher than the UTC. No significance between the treatments in the high nitrogen group, except between the A2 and K2 groups. None of the treatments with a low nitrogen baseline were able to match the high nitrogen UTC.

[0490] The results of this assay indicate that there was a positive plant response when treated with the biofertilizer diluted in Diluent #1, especially at the low nitrogen baseline. However, the results of other assays indicate that the effects could be greater when Diluent #1 steeped at a hotter temperature was used. Based on these results, Diluent # 1 appeared to be a beneficial component for Biofertilizer to be diluted into.

[0491] All treatments with the low nitrogen baseline were significantly different from the low nitrogen UTC.

[0492] Greatest plant response in aboveground fresh weight was seen when the biofertilizer was diluted in Diluent #1 and applied on top of a low nitrogen baseline.Example 4 - Expanded dilution

[0493] The purpose of this experiment was to test further diluting the biofertilizer / Dl into more DI or more water could yield any equivalent results as with the typically diluted (1.00E9 CFU / mL in DI) product. This experiment used biofertilizer and DI prepared at a steeping temperature and concentration of 95°C and lx. This specific preparation of DI has shown the most significant nitrogen replacement effects when mixed with the Biofertilizer product. This prepared mixture was diluted into water and DI at 1 Ox and lOOx dilutions and applied to plants at the same application rate.

[0494] The objectives were as follows:

[0495] To demonstrate a robust nitrogen replacement effect at 80% GSP nitrogen levels with the addition of Biofertilizer / Dl at the traditional application rate (2 oz = 1 lb N replaced) and cell density of final goods (1.00E9 CFU / mL).

[0496] To measure the relative nitrogen replacement when the product is diluted further into DI or water (at lOx and lOOx dilutions).

[0497] If a lower final cell density is used in the application of the biofertilizer products, then less robust nitrogen replacement effects was observed. However, if the product is diluted into DI, there was still some meaningful nitrogen replacement.

[0498] The goals were as follows:

[0499] Measure plant phenotypes to record plant health in response to varying fertilizer levels and microbial products.

[0500] Quantify nitrogen replacement in each treatment as % increase from the 80% GSP nitrogen control or as a % difference from the 100% GSP nitrogen control.

[0501] Experimental Design

[0502] Materials:84 - 21 -day-old lettuce seedlings 84 - 4" pots 10 mL UAN-3234 L N-Free Hoagland Solution Coconut Coir + Field & Fairway blend 25 mL Biofertilizer DI250 mL lx 95°C Dl

[0503] 7 treatment groups with 12 plants per group were treated as described in Tables12-17.Table 12 - Fertilizer dosageTable 13 - Biofertilizer CPUsTable 14 - Treatment descriptionTable 15 - Treatment timingTable 16 - Stock dilutionTable 17 - UAN application

[0504] Data Collection

[0505] Physical data:1) Aboveground Fresh-Weight and Dry-Weight2) Belowground Dry-Weight3) Scan plants at time of Harvest by Traitfinder (data not shown)4) Photos at time of Harvest (data not shown)

[0506] Nutrient data:1) Total Nitrogen of leaves (data not shown)2) NUE calculation

[0507] Results

[0508] Given a batch of biofertilizer mixed with 95°C lx DI, this experiment looked to further dilute this stock in DI and water (lOx and lOOx treatments) to determine if there was any significant nitrogen replacement effects with more dilute products, and if using water or more DI had any effect. These treatment groups were all applied to treatments atan 80% GSP nitrogen baseline, and compared to untreated controls at 80% and 100% GSP nitrogen levels to measure nitrogen replacement.

[0509] The only treatment that showed significant nitrogen replacement in terms of yield was the treatment that received the standard final goods product diluted to 1.00E9 CFUs in DI. Further dilution into water / Dl didn't provide any significant difference in aboveground yield relative to the control. See Figures 3A-3G.

[0510] Nutrient data reflected a higher Nitrogen Utilization Efficiency in the treatment group receiving the 1.00E9 CFUs in DI product. This further supported that this treatment was the top performing of all the treatments included in this trial and indicates the potential for additional nitrogen being introduced into each pot via nitrogen fixation of Xanthobacter .

[0511] This suggests that this approximate final cell density was as low as possible, while still producing a significant nitrogen replacement effect. These results also suggested that DI helped to facilitate the nitrogen-replacement effect of Xanthobacter since there was little benefit of adding a higher proportion of DI relative to the total amount of Xanthobacter autotrophicus . If DI itself had a large effect on plant yield, there would likely be a larger boost to plant yield from the treatments receiving biofertilizer diluted further into DI. Instead, the highest performing treatment is with biofertilizer and DI. The additive effects of these two components is demonstrated by the following results seen throughout this and other previous experiments:1) biofertilizer at 1.00E9 CFUs / mL diluted into water showed less significant nitrogen replacement results than Biofertilizer diluted into DI to the same final cell density; and2) Further dilution of the product into DI, and performance of DI alone showed no significant nitrogen replacement.Example 5 - Additional Diluent Testing

[0512] In Examples 5-10, additional data relating to claims and examples of diluents used with microbial fertilizers to increase efficacy and / or shelf-life was analyzed. Initial methods are described in Table 18.Table 18 - Summary table of additional results including examples tested, data generated, and recommended concentrations for each example.

[0513] Preparation of tested materials

[0514] Tomato extract: Dried tomatoes were ground into a fine powder using a spice grinder. The resulting powder was added to water in accordance with prior analysis to match the composition of the in-house diluent DI, which results in a range of 0.218-1.15 g / L.

[0515] Orange peel extract: Dried orange peels were ground into a fine powder using a spice grinder. The resulting powder was added to water in accordance with prior analysis to match the composition of the in-house diluent, which results in a range of 2.198-3.558 g / L.

[0516] Chlorella extract: Chlorella powder was added to heated water and stirred until well dispersed. The suspension was then filtered to remove insoluble material. The resulting liquid extract was prepared at various concentrations for testing in the range of 0.4-4.0 g / L.

[0517] Yeast extract: Yeast extract powder was dissolved in heated water, stirring to ensure complete solubilization. The solution was filtered to remove any undissolved particulates and prepared at various concentrations for testing in the range of 0.4-4.0 g / L.

[0518] Brewer’s yeast: Brewer’s yeast was suspended in heated water and stirred thoroughly. The solution was filtered to remove any undissolved particulates and prepared at various concentrations for testing in the range of 0.4-4.0 g / L.

[0519] Chitosan: Chitin powder was suspended in heated water and stirred continuously to aid dispersion. The solution was filtered to remove any undissolved particulates and prepared at various concentrations for testing in the range of 50-500 mg / L

[0520] Extract combo: Liquid chlorella extract and liquid yeast extract were prepared as described above at a concentration of 1.0 g / L, respectively. Chlorella and yeast extracts were combined in equal volumes. Combined extract was then diluted 5x and combined with X. autotrophicus cells for testing as described below.

[0521] Microbial combo: Microbial mixtures were made containing X. autotrophicus and one of the following: Pseudomonas fluorescens, Rhodopseudomonas palustris, Azospirillum lipoferum, Cupriavidus necator. Microbial mixtures were combined with alfalfa extract prepared at 21 g / L as a diluent and cell concentration was adjusted to 5e8 CFU / ml for A autotrophicus and 5e8 CFU / ml for the other species.

[0522] Table 19 shows Ion composition of tomato extract and orange peel extract compared to DI. These values were used to calculate estimated mass per volume of tomato and orange peel extract to match DI.Table 19 - Ion composition of DI, tomato extract, orange peel extract.Example 6 - Tomato and Orange Peel extracts

[0523] The purpose of this experiment was to test the use of Tomato and Orange peel extracts as examples of diluent for enhancing lateral root development by microbial fertilizers. Lateral root development was assessed in romaine lettuce seedlings (Lactuca sativa var. salivas. Johnny’s Selected Seeds, Winslow, Maine, USA) as follows. 50% Hoagland’s media prepared with 1.5% agar was adjusted to pH 6.5 and poured into 100 mm x 100 mm square plates. Lettuce seeds were prepared for plating by first surface sterilizing and stratifying as follows: a 2 ml sterile microcentrifuge tube was filled with500 pl of seeds along with 1 ml of 50% bleach. Seeds were exposed to bleach solution for 10 minutes after which the bleach solution was aspirated, and the seeds were washed with 1 ml of sterile water six times. Seeds were then resuspended 1 ml sterile water and placed at 4°C for 48 hours to stratify after which the water was aspirated, and seeds were stored dry at 4°C for up to 2 weeks before sowing. Sterile lettuce seeds were placed near the top of the 50% Hoagland’s agar plate along the “sowing line”. Using a pipette, 30 pl of either water (negative control) or tested product (according to Table 20 below), were plated in a single line 45 mm below the sowing line. Plates were then placed in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Plates were kept at a -80° angle during growth to encourage root growth along the agar surface. Seedlings were grown for 7 days and then root development was assessed as lateral root density determined by dividing the lateral root number of total tap root length.Table 20 - Methods for Orange and Tomato Extract

[0524] Application of Biofertilizer +D1 increased lateral root density of lettuce seedlings compared to the negative control (Figure 4). This expected result validates the outcomes of this assay. Application of Biofertilizer prepared with tomato or orange peel extract increased lateral root density compared to the negative control regardless of diluent concentration. However, only tomato extract at 0.218 g / L and orange peel extract at 2.198 g / L significantly increased lateral root density compared to the negative control.

[0525] Tomato and Orange Peel extract effect on biofertilizer.

[0526] The purpose of this experiment was to investigate the efficacy of Biofertilizer products prepared using Tomato and Orange peel extract as diluents compared to standard Biofertilizer +D1 product on lettuce. Romaine lettuce seedlings (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) are sown into trays containing sunshine mix #1. Once germinated, seedlings are watered as needed and provided weekly doses of 50% Hoagland’s solution with nitrogen to support growth. Seedlings are grownfor 21 -days before transplanting for the experimental trial. Seedlings are transplanted into 4” pots containing coconut coir potting media. Lettuce plants are grown for 28 days from transplant to harvest in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. During the growth period, plants received weekly doses of nitrogen fertilizer as UAN-32 and nitrogen free Hoagland’s solution for micronutrients. Nitrogen fertilizer was applied at 80% grower standard practice (GSP) or 100% GSP according to the treatments listed in Table 21 below. Standard Biofertilizer +D1 or Biofertilizer made with different diluents was applied as described below. Plants are watered as needed during the growth period. After 28 days of growth, lettuce plants are harvested for aboveground fresh biomass, aboveground dry biomass, and leaf tissue nitrogen (N). Leaf tissue nitrogen (%) was used to determine total leaf nitrogen by multiplying percent nitrogen and aboveground dry biomass. Nitrogen use efficiency crop (NUEcrop) was calculated as total leaf nitrogen divided by nitrogen supplied as fertilizer.Table 21 - Tomato and Orange Peel extract treatment

[0527] Application of Standard Biofertilizer +D1 significantly increased fresh and dry biomass of lettuce compared to 80% GSP control. Application of Biofertilizer prepared with tomato or orange peel extract also significantly increased aboveground fresh and dry biomass of lettuce compared to 80% GSP control (Figures 5A-5B). Of these treatments, the use of tomato extract at 0.218 g / L and orange peel extract at 2.198 g / L resulted in slightly greater increases in biomass compared to the other concentrations of those extracts.

[0528] Furthermore, leaf tissue nitrogen content, total leaf nitrogen, and nitrogen use efficiency of lettuce was comparable to control (Figures 6A-6C).Example 7 - Yeast Extract and / or Chlorella Extracts as a Diluent

[0529] The purpose of this experiment was to test the use of Yeast, Brewer’ s yeast, Chlorella, and Yeast + Chlorella extracts as examples of diluent for enhancing lateral root development by microbial fertilizers. Lateral root development was assessed in romaine lettuce seedlings (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) as follows. 50% Hoagland’s media prepared with 1.5% agar was adjusted to pH 6.5 and poured into 100 mm x 100 mm square plates. Lettuce seeds were prepared for plating by first surface sterilizing and stratifying as follows: a 2 ml sterile microcentrifuge tube was filled with 500 pl of seeds along with 1 ml of 50% bleach. Seeds were exposed to bleach solution for 10 minutes after which the bleach solution was aspirated, and the seeds were washed with 1 ml of sterile water six times. Seeds were then resuspended 1 ml sterile water and placed at 4°C for 48 hours to stratify after which the water was aspirated, and seeds were stored dry at 4°C for up to 2 weeks before sowing. Sterile lettuce seeds were placed near the top of the 50% Hoagland’s agar plate along the “sowing line”. Using a pipette, 30 pl of either water (negative control) or tested product (according to Table 22 below), were plated in a single line 45 mm below the sowing line. Plates were then placed in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Plates were kept at a -80° angle during growth to encourage root growth along the agar surface. Seedlings were grown for 7 days and then root development was assessed as lateral root density determined by dividing the lateral root number of total tap root length.Table 22 - Methods for yeast extract and chlorella extract analysis

[0530] Application of Standard Biofertilizer +D1 increased lateral root density of lettuce seedlings compared to the negative control (Figure 7). This expected result validates theoutcomes of this assay. Application of Biofertilizer prepared with alternative diluent produced results that were in between the controls, with the use of Yeast Extract (0.4 g / L) as a diluent resulting in the most lateral roots per cm in compared to other candidate diluents.

[0531] Lateral root development after treatment with diluent derived from Yeast, Brewer’s yeast, Chlorella, and / or Yeast + Chlorella extracts.

[0532] The purpose of this experiment was to test the use of Yeast, Brewer’ s yeast, Chlorella, and Yeast + Chlorella extracts as examples of diluent for enhancing lateral root development by microbial fertilizers. Lateral root development was assessed in romaine lettuce seedlings (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) as follows. 50% Hoagland’s media prepared with 1.5% agar was adjusted to pH 6.5 and poured into 100 mm x 100 mm square plates. Lettuce seeds were prepared for plating by first surface sterilizing and stratifying as follows: a 2 ml sterile microcentrifuge tube was filled with 500 pl of seeds along with 1 ml of 50% bleach. Seeds were exposed to bleach solution for 10 minutes after which the bleach solution was aspirated, and the seeds were washed with 1 ml of sterile water six times. Seeds were then resuspended 1 ml sterile water and placed at 4°C for 48 hours to stratify after which the water was aspirated, and seeds were stored dry at 4°C for up to 2 weeks before sowing. Sterile lettuce seeds were placed near the top of the 50% Hoagland’s agar plate along the “sowing line”. Using a pipette, 30 pl of either water (negative control) or tested product (according to Table 23 below), were plated in a single line 45 mm below the sowing line. Plates were then placed in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Plates were kept at a -80° angle during growth to encourage root growth along the agar surface. Seedlings were grown for 7 days and then root development was assessed as lateral root density determined by dividing the lateral root number of total tap root length.Table 23 - Lateral root development treatments

[0533] Application of Standard Biofertilizer +D1 increased lateral root density of lettuce seedlings compared to the negative control (Figure 8). This expected result validates the outcomes of this assay. The application of Biofertilizer prepared with 0.4 g / L yeast extract resulted in similar lateral root density as standard Biofertilizer. Only standard Biofertilizer +D1 and Biofertilizer prepared with 0.4 g / L of yeast extract statistically increased lateral root density compared to the negative control. All other diluent candidates resulted in a non-significant increase in lateral root density compared to the negative control.

[0534] Diluent effect on seedlings.

[0535] The purpose of this experiment was to investigate the efficacy of Biofertilizer products prepared using Yeast extract, Chlorella extract, Yeast extract + Chlorella extract, or Chitosan as diluents compared to standard Biofertilizer + DI product on lettuce. Romaine lettuce seedlings (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) are sown into trays containing sunshine mix #1. Once germinated, seedlings are watered as needed and provided weekly doses of 50% Hoagland’s solution with nitrogen to support growth. Seedlings are grown for 21 -days before transplanting for the experimental trial. Seedlings are transplanted into 4” pots containing coconut coir potting media. Lettuce plants are grown for 28 days from transplant to harvest in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. During the growth period, plants received weekly doses of nitrogen fertilizer as UAN-32 and nitrogen free Hoagland’s solution for micronutrients. Nitrogen fertilizer was applied at 80% grower standard practice (GSP) or 100% GSP according to the treatments listed in Table 24 below. Standard Biofertilizer + DI or Biofertilizer made with different diluents was applied as described below. Plants are watered as needed during the growth period. After 28 days of growth, lettuce plants are harvested for aboveground fresh biomass, aboveground dry biomass, and leaf tissue nitrogen (N). Leaf tissue nitrogen (%) was used to determine total leaf nitrogen by multiplying percent nitrogen and aboveground dry biomass. Nitrogen utilization efficiency crop (NUEcrop) was calculated as total leaf nitrogen divided by nitrogen supplied as fertilizer.Table 24 - Seedling treatments

[0536] Application of standard Biofertilizer +D1 and Biofertilizer with cells only at lOx fold higher cell concentration significantly increased lettuce aboveground biomass over the 80% GSP control and was statistically similar to the 100% GSP control (FIG. 9). Biofertilizer prepared with Yeast extract, Chlorella + Yeast Extract, and Chitosan increased aboveground biomass compared to the 80% GSP control, but this increase was not statistically significant. FIGs. 10A-10C show Leaf tissue nitrogen content (FIG.10A), total leaf nitrogen (FIG. 10B), and nitrogen use efficiency crop (FIG. 10C) data of lettuce grown in pots.Example 8 - Rice Hull as a diluent

[0537] Brewer’s Diluent Preparation.

[0538] Purpose: Determine optimal mixing ratios of rice hulls (RH or rice husk) for D2 preparation. Different concentrations (lx, 2x, 5x) were based on the standard diluent (alfalfa extract, DI) weight by volume ratio of 21.1 g / L. D2 formulation of 21.1 g / L is also labeled as a lx concentration. Formulations were prepared with DI water.

[0539] Physical properties.

[0540] Design: Four IL batches of RH in distilled water were prepared to test physical properties of RH during extraction. Formulations were made in an electric kettle, set for steeping at 95°C (actual temperature range of 199-200°F = 92.8-96.1°C) for 1 hour before being decanted through different porosity filters for collection. All formulations were made in 500 mL volumes with TDC tap water.

[0541] Results: lOx RH - (211 g / L) Kettle overheated because liquid could not circulate - resulting product was a thick, sludgy porridge like consistency with very little freeliquid. The resulting product could not be filtered through a coarse mesh sieve or coffee filter in any meaningful way. 5x RH - (105.5 g / L) Kettle heated as expected and mixture remained more flowable. Extract was filtered through coarse mesh sieve, large volume of solids remained behind, only retrieved -250 mL of liquid out of the original 500 mL once the solids were separated. Unable to filter mixture through coffee filter - milky opaque appearance with lots of suspended fine particles. Centrifuging a small sample at 15000 x g for 5 min pelleted -25% as solids, 65% as a milky aqueous phase and -10% as a possible white lipid or cellulose (lighter than water) phase at the top. The aqueous phase was not filterable through a 0.22 pm syringe filter, despite the centrifugation. 2x RH - (42.2 g / L) Produced a very thick solution, but more flowable than the 5x. The bulk of the liquid was also difficult to separate, and the small particle density was too high for any of our filtration techniques. Many of the small partial rice particles left in the dry material had absorbed water and bulked up in this version, lx RH - (21.1 g / L) Particulate matter from RH settles to the bottom of the vessel after standing, and separates into a solid phase and a decantable liquid phase.

[0542] Alternative preparation methods.

[0543] Design: Trial investing alternative preparation methods including autoclaving RH diluent as an alternative to filter sterilization and cold steeping for extraction. Prepared three formulations for testing using TDC tap water.

[0544] Results: Formulation 1 - lx RH (21 g / L) autoclaved at 121°C for 30 minutes, cooled then placed in fridge overnight (-14 hours). Three distinct layers / phases of the product emerged after the bottle adjusted to room temperature (Image 1). Upper phase was foamy and paler / white in color, floating on the surface of the solution. The upper phase was not homogenous and is present at different thicknesses around the circumference of the bottle. The upper phase mixes at an interface with the middle phase and did not have a clear border. Middle phase was turbid and beige with fine solids. This phase was pipetted without sticking or retention and filter sterilization was possible with smaller aliquots. Lower phase consisted of two portions, a layer of fine solids that have sedimented out and non-dissolved chunky solids and rice hull pieces at the bottom. The middle phase was drawn off using a serological pipette and filtered through a 5 pm and 1.2 pm filter. After filtration through the larger pore sizes, attempted to pass the filtratethrough a 0.22 gm syringe filter, which clogged immediately. A 0.22 gm filter bottle was then tried, however the larger filtration surface area still clogged after only ~25 mL.

[0545] Formulation 2 - lx RH (21.1 g / L) RH were cold steeped 4°C overnight (~16 hours). Two noticeable phases were present in this formulation. Upper phase showed a gradient of dissolved solids. The upper part of the top phase was light beige and slightly translucent and the lower part of the top phase was beige comparatively more turbid - more similar to the middle phase of the autoclaved solution above. There was a slight white film at the top. Lower phase consisted of undissolved RH pieces and was more homogenous than the lower phase of the formulation 1. The cold steeped version was nearly entirely clarified overnight. 5 mL of supernatant was drawn off and filtered through a single 0.22 pm syringe filter rapidly.

[0546] Formulation 3 - lx RH (21.1 g / L) was steeped at 95°C for 1 hour, then cooled and placed in fridge overnight (14 hours). Two noticeable phases were present in this formulation, it was intermediate between the autoclaved and cold steeped version. Upper phase was a turbid beige with less translucence than the formulation 2 upper phase, but less color than the autoclaved version. Some foaminess and flecks of material stayed on the surface. Lower phase consisted of undissolved RH pieces and had a thinner layer of settled fine solids compared to formulation 1. The middle phase was drawn off using a serological pipette and filtered through a 5 pm and 1.2 pm filter as with the autoclaved version. After filtration through the larger pore sizes, the remainder was passed through 0.22 pm filter bottles, with a final yield of around 40 mL total from 80 mL sampled.

[0547] Different Steeping Temperatures.

[0548] Purpose: Samples from the diluent preparation trials were analyzed via ion chromatography (IC) for ionic composition. The aim was to determine which extraction temperature of RH achieved the highest extracted ion content.

[0549] All samples were 0.22 pm filtered before submission using syringe filters and 10 mL syringes. Formulation 2 diluent filtered easily, the Formulation 1 and 3 had significantly more solids in suspension and required multiple filters to get the 10 mL of sample for analysis.Table 25 - Ion content (in PPM) of each RH formulation.

[0550] Continued Steeping.

[0551] Purpose: Two samples, Formulation 2 and Formulation 1, were analyzed for ion composition on IC following an additional 9 days of storage with the solid RH fraction. Extracts were stored at 4°C in the fridge for 9 days following the first IC analysis to determine if any additional ions continued to dissolve into solution. The samples were treated with the same filtration protocol as described above.Table 26 - Ion content (in PPM) of each Formulation and test time point. Bold rows indicate ions with a greater than 20% change in concentration between the two time points.

[0552] Flask Culture Media Addition and Replacement.

[0553] Purpose: RH extract has the potential not only as a diluent but as a substrate for X. autotrophicus growth. The purpose of these experiments were to determine whether RH can replace the yeast extract in the fermentation media used to produce X autotrophicususing MSDH process (4 g / L yeast extract) or enhance growth with a boosting effect. 4 g / L addition or substitution was chosen to mimic the amount of yeast extract (YE).

[0554] Design: Three treatments in biological duplicates (6 flasks) were prepared for this experiment. Each 250 mL flask was filled with 50 mL of treatment media, and inoculated targeting a 1E7 CFU / mL density with 50 pL of Biofertilizer. Flasks were started with and fed daily 100 mM methanol (190 pl) for the first 5 days. Day 6 was not sampled or fed, and day 7 the flasks were sampled and the experiment ended.

[0555] Cell concentrations were monitored over the experiment with daily CFU plating, in technical duplicates across a likely dilution range. Aliquots (1.5 ml) were collected daily for CFU plating and stored at 4°C in case of additional testing requirements. Media pH and electrical conductivity (EC) were tested after preparation, values were recorded when analyte was at 27°C (Table 27). Additionally, 500 pl samples were pulled from each flask at the final sampled time point for ODeoo PHB quantification using the established protocol. Samples were blanked with a pre-inoculation DO aliquot. Single samples were processed for each flask.Table 27 - pH and electroconductivity (mS / cm) for each media before inoculation.

[0556] Results: Cultures grown in the RH “Boost” treatment aligned closely with the control treatment, while cultures in the RH “Replacement” treatment achieved -40% of cell density (CFU / ml) of the control treatment (Figure 11). All ODeoo values read on the spectrophotometer were too low, out of the reliable reading range. However, values were still recorded and corrected for dilution (Figure 12). Samples containing RH still had floating flecks of material after the bleach digestion that may interfere with absorbance measurements.

[0557] Modified Flask Culture Media Addition and Replacement.

[0558] Design: To confirm findings, the flask culture media addition and replacement design was repeated with modifications including a reduced incubation time from 7 days to 4 days. Biological duplicate flasks were plated singly at each time point instead of technical duplicates. Additionally, flasks were not sampled or fed 100 mM MeOH on day 3.

[0559] Results: Cultures grown in the RH “Boost” treatment aligned closely with the control treatment, while cultures in the RH “Replacement” treatment achieved -70% of cell density (CFU / ml) of the control treatment (Figure 13).

[0560] Diluent Compatibility.

[0561] Purpose: Autoclaved RH (Formulation 1) contained many dissolved ions that may affect X. autotrophicus survival when used as a diluent for storage. From diluent formulation trials above, the formulation 1 preparation method was chosen as optimal for workability and sterility. From this formulation, the middle phase (aqueous, without the floating white layer at the top and settled solids from the bottom) was used in diluent formulations, since it was homogenous and sterile.

[0562] Purpose: Identify an optimum RH concentration for supporting / maintaining cell viability in storage at 4°C or room temperature.

[0563] Design: Formulation 1 was used for all experiments, hereafter referred to as lx D2 (21.1 g / L of rice hull). Liquid from middle phase of formulation 1 was removed with a serological pipette, vortexed, and then used for relevant treatments. Test samples were prepared using biofertilizer with cells only, which was produced from a bioreactor culture containing X. autotrophicus cells. Controls representing standard Biofertilizer + DI were prepared using standard DI diluent. All mixtures were prepared to a starting cell density of le9 CFU / ml. Five aliquots of 8 mL were prepared per treatment and stored in 15 mL aliquots in a refrigerator at 4°C for 27 days. After 6 days a subset of samples were moved to room temperature (~25°C) and placed in a cabinet after plating, then sampled non- destructively repeatedly over 18 days. All samples from both storage temperatures were plated in triplicate at the -E6 dilution. See FIG. 14.Table 28 - Composition of Round 1 diluent trial treatments.

[0564] Results: At 4°C, there was little to no observable decline in CFUs over 21 days and no significant difference between standard Biofertilizer + DI and test samplescontaining RH diluent (D2). Under room temperature conditions, lower concentrations of D2 maintained higher cell densities by the end of the trial at RT. Formulations containing 0.5x and 0.25x D2 had similar CFU counts at the end of the trial to the standard Biofertilizer + DI, while both formulations containing full strength (lx) D2 had reduced CFU counts. See FIGs. 15-16.

[0565] Purpose: Repeat best performing formulations at 25°C. Additional treatments including X. autotrophicus in water (Biofertilizer with cells only + water) as a control along with an additional diluent mixture (0.25x D2+ lx DI) were also added.

[0566] Design: Formulation 1 was used for all experiments, hereafter referred to as lx D2 (21.1 g / L of rice hull). Liquid from middle phase of formulation 1 was removed with a serological pipette, vortexed, and then used for relevant treatments. Test samples were prepared using biofertilizer with cells only and controls representing biofertilizer + DI were prepared using standard DI diluent. A single, non-destructive 5 mL aliquot was used for repeated sampling. Samples were plated in triplicate at the -E6 dilution with a single biological replicate. All samples were incubated at 25°C.Table 29 - Composition of diluent trial treatments

[0567] Results: All treatments converged on a similar CFU / mL at the end of the study period. Fluctuations observed in plate counts may be due to delayed growth after potentially stressful period at 25°C. More colonies appeared if plates were retained at room temperature for an additional 2 days and were added to the counts for the samples plated at day 28 and day 38, but not the previously plated samples. Day 28 samples were a replate of strange day 26 results. See FIG. 17.

[0568] High cell density trials.

[0569] Purpose: Test whether starting diluent treatment concentrations at a higher cell density impacts cell survival over time at 25°C when using the most promising diluent candidate from previous trials, 0.25x D2.

[0570] Design: Formulation 1 was used for all experiments, hereafter referred to as lx D2 (21.1 g / L of rice hull). Liquid from middle phase of formulation 1 was removed with a serological pipette, vortexed, and then used for relevant treatments. Test samples were prepared using X. autotrophicus bioreactor samples. Controls representing biofertilizer + DI were prepared using standard DI diluent. A single, non-destructive 10 mL aliquot was used for repeated sampling. Plating was performed in triplicate for each treatment, with a single biological replicate. Samples were stored at 25°C.Table 30 - Composition of higher density diluent trial treatments.

[0571] Results: High cell density (5E9 or 1E10 CFU / ml) treatments generally declined faster than lower cell density samples. The highest cell density 1E10 treatment declined the most overall by log-fold change. The Biofertilizer formulation with 0.25x D2 did not decline over time, showing similar stability to standard Biofertilizer + DI. See FIG. 18 and FIG. 19

[0572] Lettuce Tissue Culture Trials.

[0573] Purpose: An ideal diluent for X. autotrophicus product would not only provide a storage medium but increase plant growth through some mechanism - either on its own or synergistically. For RH to be a viable diluent candidate it needs to be at least as efficacious as or better than DI in storage and plant growth promotion or pose some other benefit. Combinatorial treatments of DI and D2 may behave differently than either diluent alone when combined with A. autotrophicus biofertilizer. Test how RH diluent and formulations perform when compared to the Biofertilizer + DI and controls in lettuce seedling tissue culture vessel plant trials.

[0574] Design: Eight replicate Magenta™ Vessels per treatment were prepared for tissue culture with 100 mL of 50% concentration Hoagland’s nutrient, 0.8% agar, with 2.5 g / L glucose. Romaine Lettuce seeds (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) were surface sterilized and stratified at 4°C for 48 hours prior to germination on 50% Hoagland’s nutrient agar plates stored in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Seeds were germinated for only 3 days compared to the average 4 days prior to transplant. Seedlings with root lengths of approximately 1 cm were transplanted into the Magenta™ Vessels.

[0575] Treatment media was prepared with biofertilizer and DI diluent or Formulation 1 D2 and applied to seedlings transplanted into Magenta™ vessels in 10 pL volumes. All treatment media formulations, other than the negative control, were made to a calculated 1.5E9 CFU / mL density. Seedlings were grown for 3 weeks in a growth chamber with 16- hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% before being harvested for fresh vegetative biomass measurements, excluding roots. Treatments and calculations for stock preparations are as described in Table 31.Table 31 - Treatment composition for lettuce trials.

[0576] Results: Results show no statistically significant differences in biomass between the control seedling biomass and the Biofertilizer + DI or Biofertilizer with cells only control treatments. No significantly negative effects of D2 on plant biomass were recognized in this experiment. Potential reasons for this result could be due to issues with seed health and germination. Following this experiment, lettuce seeds germinated from the same lot were tested, and had a low germination rate (approximately 50% compared to typical 90%) and the leaves of germinated seedlings showed unusual browning along the cotyledon mid ribs. See FIG. 20 and FIG. 21. Experiment was refined based on diluent trials and repeated.

[0577] Redefined Lettuce Tissue Culture Trials.

[0578] Design: Ten replicate Magenta™ Vessels per treatment were prepared for tissue culture with 100 mL of 50% concentration Hoagland’s nutrient, 0.8% agar, with 2.5 g / Lglucose. Bromothymol blue was incorporated into the media starting with round 2, a color change indicator that turns blue as the agar media becomes more basic. X. autotrophicus ’ nitrogen fixation pathway is hypothesized to drive this change, and it can be used as an early indicator of nitrogen fixation activity before harvest.

[0579] Romaine Lettuce seeds (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) were surface sterilized and stratified at 4C for 48 hours prior to germination on 50% Hoagland’s nutrient agar plates incubated in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% 3 days. Seeds were germinated for 96 hours. Seedlings with root lengths of approximately 1-1.5 cm were transplanted into the Magenta™ Vessels.

[0580] Treatment media was prepared with biofertilizer and DI diluent or Formulation 1 D2 and applied to seedlings transplanted into MagentaTM vessels in 10 pL volumes. All treatment media formulations, other than the negative control, were made to a calculated 1.5E9 CFU / mL density. Seedlings were grown for 3 weeks in a growth chamber with 16- hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% before being harvested for fresh vegetative biomass measurements, excluding roots. Treatments and calculations for stock preparations are as described in Table 32.Table 32 - Composition of redefined lettuce trial treatments.

[0581] Results: Biofertilizer with cells only and Biofertilizer + DI control treatments have statistically greater average biomasses compared to the average biomass of the Water Control treatment in this trial demonstrating the trial performed as expected. Biomass from treatments containing RH diluent (D2) were statistically similar to the Biofertilizer + DI control treatment. See FIG. 22 and FIG. 23.

[0582] Lower density X. autotrophicus in lettuce trials.

[0583] Design: Nine replicate Magenta™ Vessels per treatment were prepared for tissue culture with 100 mL of 50% concentration Hoagland’s nutrient, 0.8% agar, with 2.5 g / L glucose. Bromothymol blue was incorporated into the media starting with round 2, a color change indicator that turns blue as the agar media becomes more basic. X. autotrophicus ’ nitrogen fixation pathway is hypothesized to drive this change, and it can be used as an early indicator of nitrogen fixation activity before harvest.

[0584] Romaine Lettuce seeds (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) were surface sterilized and stratified at 4°C for 48 hours prior to germination on 50% Hoagland’s nutrient agar plates incubated in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% for 3 days. Seeds were germinated for 96 hours. Seedlings with root lengths of approximately 1-1.5 cm were transplanted into the Magenta™ vessels.

[0585] Treatment media was prepared with biofertilizer and DI diluent or Formulation 1 D2 and applied to seedlings transplanted into Magenta™ vessels in 10 pL volumes. Seedlings were grown for 3 weeks in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% before being harvested for fresh vegetative biomass measurements, excluding roots. Treatments and calculations for stock preparations are as described in Table 33Table 33 - Composition of lower density treatments.

[0586] Results: Biofertilizer with cells only and Biofertilizer + DI Control treatments have statistically greater average biomasses compared to the average biomass of the Water Control treatment in this trial. Biomass from treatments containing RH diluent (D2) were statistically similar to the Biofertilizer + DI control treatment. See FIG. 24 and FIG. 25Example 9 - Combined Microorganisms and Diluent

[0587] The purpose of this experiment was to test efficacy of combined microorganisms with diluent for enhancing lateral root development by microbial fertilizers. Lateral root development was assessed in romaine lettuce seedlings (Lactuca sativa var. salivus, Johnny’s Selected Seeds, Winslow, Maine, USA) as follows. 50% Hoagland’s media prepared with 1.5% agar was adjusted to pH 6.5 and poured into 100 mm x 100 mm square plates. Lettuce seeds were prepared for plating by first surface sterilizing and stratifying as follows: a 2 ml sterile microcentrifuge tube was filled with 500 pl of seeds along with 1 ml of 50% bleach. Seeds were exposed to bleach solution for 10 minutes after which the bleach solution was aspirated, and the seeds were washed with 1 ml of sterile water six times. Seeds were then resuspended 1 ml sterile water and placed at 4°C for 48 hours to stratify after which the water was aspirated, and seeds were stored dry at 4°C for up to 2 weeks before sowing. Sterile lettuce seeds were placed near the top of the 50% Hoagland’s agar plate along the “sowing line”. Using a pipette, 30 pl of either water (negative control) or tested product (according to Table 34 below), were plated in a single line 45 mm below the sowing line. Plates were then placed in a growth chamber with 16- hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Plates were kept at a -80° angle during growth to encourage root growth along the agar surface. Seedlings were grown for 7 days and then root development was assessed as lateral root density determined by dividing the lateral root number of total tap root length.

[0588] In this experiment, Standard Biofertilizer containing bioreactor grown X. autotrophicus was used as a positive control. For all microbial mixtures, bacteria including X. autotrophicus, Pseudomonas fluorescens, Rhodopseudomonas palustris, Azospirillum lipoferum, Cupriavidus necator were grown in flasks of nutrient broth (NB) in a shaking incubator at 30°C and 200 rpm. Flasks were grown for 24 hours and then cultures were adjusted to a cell density of le9 CFU / ml based on an OD600 of 0.57. Adjusted cultures were then used to prepare test samples as described above.Table 34 - Lateral root development in lettuce treatments.

[0589] Application of Biofertilizer + DI increased lateral root density of lettuce seedlings compared to the negative control (FIG. 26). This expected result validates the outcomes of this assay. Application of Biofertilizer prepared with tomato or orange peel extract increased lateral root density compared to the negative control regardless of diluent concentration. However, only tomato extract at 0.218 g / L and orange peel extract at 2.198 g / L significantly increased lateral root density compared to the negative control.Example 10 - Freeze Dried fermentate with liquid diluents

[0590] Purpose: To investigate and confirm the efficacy of dry product formulations using four distinct experimental approaches.

[0591] Across the four experiments listed below dry products were prepared for application to plants in a range of ways. Below is a treatment key describing how each version was prepared.

[0592] Freeze Dry Formulation VI : VI uses a freeze dried fermentate with a liquid diluent. VI is prepared by first resuspended the freeze dried fermentate powder in water before combining with diluent. This is then applied as a standard liquid product at ~le9 CFU / ml.

[0593] Freeze Dry Formulation VI - cells only: VI - biofertilizer with cells only used a freeze dried fermentate. VI - biofertilizer with cells only is prepared by resuspending the freeze dried fermentate in water before applying directly to plants as a liquid at ~lel0 CFU / ml. Diluent is not included in this version.

[0594] Freeze Dry Formulation V2: V2 uses a freeze dried biofertilizer + DI which includes fermentate and diluent dried together. V2 is prepared by resuspending the freeze dried finished product in water before applying directly to plants as standard liquid product at ~le9 CFU / ml.

[0595] Freeze Dry Formulation V3: V3 uses a freeze dried fermentate and freeze dried diluent which are dried separately. V3 is prepared by resuspending the freeze driedfermentate in water and resuspending the freeze dried diluent in water. Resuspended fermentate and diluent are then combined to prepare standard liquid product. This is applied to plants as standard liquid product at ~le9 CFU / ml.

[0596] Freeze Dry Formulation V4: V4 uses a liquid fermentate and a freeze dried diluent. V4 is prepared by first resuspending the freeze dried diluent in water and then combining with liquid fermentate to prepare standard liquid product. This is applied to plants as standard liquid product at ~le9 CFU / ml.

[0597] Lateral Root Assay.

[0598] The purpose of this experiment was to investigate the ability of dry Biofertilizer formulation to enhance root development of lettuce seedlings compared to the standard liquid Biofertilizer. Lateral root development was assessed in romaine lettuce seedlings (Lactuca sativa var. salivus) as follows. 50% Hoagland’s media prepared with 1.5% agar was adjusted to pH 6.5 and poured into 100 mm x 100 mm square plates. Lettuce seeds were prepared for plating by first surface sterilizing and stratifying as follows: a 2 ml sterile microcentrifuge tube was filled with 500 pl of seeds along with 1 ml of 50% bleach. Seeds were exposed to bleach solution for 10 minutes after which the bleach solution was aspirated, and the seeds were washed with 1 ml of sterile water six times. Seeds were then resuspended 1 ml sterile water and placed at 4°C for 48 hours to stratify after which the water was aspirated, and seeds were stored dry at 4°C for up to 2 weeks before sowing. Sterile lettuce seeds were placed near the top of the 50% Hoagland’s agar plate along the “sowing line”. Using a pipette, 30 pl of either water (negative control) or tested product (according to Table 35 below), were plated in a single line 45 mm below the sowing line. Plates were then placed in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. Plates were kept at a -80° angle during growth to encourage root growth along the agar surface. Seedlings were grown for 7 days and then root development was assessed as lateral root density determined by dividing the lateral root number of total tap root length.Table 35 - Treatments in the Lateral Root Assay

[0599] Application of Biofertilizer + DI, Freeze Dry Formulation VI - cells only, Freeze Dry Formulation VI, and Freeze Dry Formulation V3 all increased lateral root density of lettuce seedlings compared to the negative control (Figure 31). Application of Freeze Dry Formulation VI resulted in the greatest lateral root density. These results demonstrate root development of lettuce is similarly enhanced by standard liquid product and tested dry formulations.

[0600] Tissue Culture Assay.

[0601] The purpose of this experiment was to investigate the efficacy of a dry Biofertilizer formulation relative to the standard liquid Biofertilizer + DI product on lettuce under optimized growth conditions. Romaine lettuce seedlings (Lactuca sativa) were surface sterilized as described in experiment #1 above. Sterile seeds were plated onto 50% Hoagland’s agar plates and germinated for 5 days before transplanting to tissue culture systems. Seedlings were transplanted into tissue culture vessels containing 50% Hoagland’s agar. Seedlings were then treated with 10 pl of water or 10 pl of product according to table 36 below. This volume of product delivered le7 CFU of microbial cells per plant. Plants were grown for 21 days in a growth chamber with 16-hour day / 8- hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50% before harvesting for aboveground fresh biomass.Table 36 - Treatments in the Tissue Culture Assay

[0602] Application of Biofertilizer + DI, Freeze Dry Formulation VI - cells only,Freeze Dry Formulation VI, and Freeze Dry Formulation V2 all significantly increased aboveground biomass of lettuce compared to application of water only in a 50%Hoagland growth environment (Figure 32). These results demonstrate a similar potential for Freeze Dry formulations and Biofertilizer + DI standard liquid product to enhance lettuce growth under tissue culture conditions.

[0603] Lettuce Pot Trial.

[0604] The purpose of this experiment was to investigate the efficacy of a dry Biofertilizer formulation relative to the standard liquid Biofertilizer + DI product on lettuce. Romaine lettuce seedlings (Lactuca sativa) are sown into trays containing sunshine mix #1. Once germinated, seedlings are watered as needed and provided weekly doses of 50% Hoagland’s solution with nitrogen to support growth. Seedlings are grown for 21 -days before transplanting for the experimental trial. Seedlings are transplanted into 4” pots containing coconut coir potting media. Lettuce plants are grown for 28 days from transplant to harvest in a growth chamber with 16-hour day / 8-hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. During the growth period, plants received weekly doses of nitrogen fertilizer as UAN-32 and nitrogen free Hoagland’s solution for micronutrients. Nitrogen fertilizer was applied at 80% grower standard practice (GSP) or 100% GSP according to the treatments listed in Table 37 below. Biofertilizer (liquid or dry formulation) was applied as described below. Plants are watered as needed during the growth period. After 28 days of growth, lettuce plants are harvested for aboveground fresh weight and leaf tissue nitrogen (N). Leaf tissue nitrogen (%) was used to determine total leaf nitrogen by multiplying percent nitrogen and aboveground dry biomass. Nitrogen use efficiency crop (NUEcrop) was calculated as total leaf nitrogen divided by nitrogen supplied as fertilizer.Table 37 - Lettuce Pot Trial Treatments

[0605] Application of Biofertilizer + DI and Freeze Dry Formulation VI significantly increased aboveground biomass of lettuce compared to the low nitrogen control of 80% GSP (Figure 33). The application of Freeze Dry Formulation V2 did not significantly increase aboveground biomass of lettuce compared to the 80% GSP treatment. Percentleaf tissue N was lower in all biofertilizer treatments compared to the 80% GSP (Figures 34A-34C). However, total leaf N and NUEcrop was greater in the Biofertilizer + DI and Freeze Dry Formulation VI treatments compared to the 80% GSP (Figure 35). These results demonstrate similar efficacy of Biofertilizer + DI and Freeze Dry Formulation VI on lettuce indicating that freeze dried fermentate can be successfully resuspended without efficacy loss.

[0606] Tomato Pot Trial

[0607] The purpose of this experiment was to investigate the efficacy of a dry biofertilizer formulation relative to the standard liquid Biofertilizer + DI product on tomatoes. Micro tomato seedlings (Solanum lycopersicum) were sown into trays containing sunshine mix #1. Once germinated, seedlings are watered as needed and provided weekly doses of 50% Hoagland’s solution with nitrogen to support growth. Seedlings are grown for 40 days before transplanting for the experimental trial. Seedlings are transplanted into 4” pots containing coconut coir potting media. Tomato plants are grown for 8 weeks from transplant to harvest in a growth chamber with 16-hour day / 8- hour night light cycles, temperatures at 25°C during the day and 22°C at night, and humidity maintained at 50%. During the growth period, plants received weekly doses of nitrogen fertilizer as UAN-32 and nitrogen free Hoagland’s solution for micronutrients. Nitrogen fertilizer was applied at 50% GSP or 100% GSP according to the treatments listed in Table 38 below. Biofertilizer (liquid or dry formulation) was applied using two different volumes of water for delivery as described in Table 38 below. Plants are watered as needed during the growth period. After 8 weeks of growth, lettuce plants are harvested for aboveground vegetative biomass and fruit yield. Fruit yields were recorded as total mass of fruit per plant, total mass of red fruit per plant, and total fruit counts per plant. Average fruit size was calculated by dividing total fruit mass per plant by total fruit counts per plant.Table 38 - Treatments for Tomato Pot trial

[0608] Application of Biofertilizer + DI and Freeze Dry Formulation VI, regardless of water delivery volume, did not significantly increase the vegetative biomass of tomatoes (Figure 35). Though not statistically significant, the application of Biofertilizer + DI and Freeze Dry Formulation VI tended to increase the total fruit yield per plant regardless of water delivery volume (Figure 36A). Total fruit yield per plant tended to be greater than both the 50% GSP and 100% GSP treatments for all biofertilizer or freeze-dry treated plants. Only the application of Freeze Dry Formulation VI in 40 ml of water meaningfully increased the mass of red fruit yield per plant over the 50% GSP and 100% GSP treatments (Figure 36B). Additionally, the application of Biofertilizer + DI in 20 ml of water and Freeze Dry Formulation VI at both water delivery volumes tended to increase total fruit numbers over the 50% GSP and 100% GSP treatments (Figure 36C). Average fruit size was consistent across all treatments with a slight trend towards larger mass fruits in the 50% GSP treatment (Figure 36D). These results demonstrate similar efficacy between Biofertilizer + DI standard liquid product and Freeze Dry Formulation VI when applied to tomatoes.* * *
