[0001] A PCT Request Form is filed concurrently with this specification as part of the present application. Each application that the present application claims benefit of or priority to as identified in the concurrently filed PCT Request Form is incorporated by reference herein in their entireties and for all purposes.FIELD
[0002] The present disclosure relates to fungal proteases, formulations including proteases, compositions formed by treatment with proteases, as well as methods thereof.BACKGROUND
[0003] Modern agricultural techniques rely on various chemicals to provide pathogen control and growth stimulation. There is an increased emphasis and awareness of the effects that such chemicals can have, not only on crop production, but also on environmental impact.
[0004] The background description provided herein is for the purposes of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise constitute prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.SUMMARY
[0005] The present disclosure relates to fungal proteases, which can be provided in a formulation. The protease-containing formulation can include one or more carriers or additives configured for using the protease in hydrolyzing plant proteins or feedstock. Proteases derived from Trichoderma can be of particular use. Thus, in some embodiments, the protease formulation includes one or more Trichoderma proteases. The formulation can include other inert ingredients that do not necessarily provide proteolytic activity. However, such inert ingredients can affect the activity of the proteases. For instance, such inert ingredients can include those that stabilize the protease or enhance activity of the protease upon addition to a feedstock.
[0006] A protease formulation, in turn, can be used to treat a feedstock, thereby producing a hydrolysis product. Such hydrolysis products are referred to as compositions and formulations thereof, depending on whether an inert ingredient is added. For example, a hydrolysis product (e.g., as a direct result of feedstock treated with a protease or a protease formulation) is generallyreferred to as a composition, whereas such a hydrolysis product having an added inert ingredient (e.g., water, oil, etc.) is generally referred to as a formulation.
[0007] Thus, also described herein are compositions treated with fungal proteases, as well as methods for preparing and using such compositions. For instance, the composition can be prepared by treating a plant protein or a feedstock with a protease formulation, thereby providing protease-treated components within the hydrolyzed composition. The hydrolyzed composition, in turn, can include one or more other additives (e.g., nutrients), thereby providing a hydrolyzed formulation.
[0008] In particular embodiments, the hydrolyzed composition and / or the hydrolyzed formulation have potential as a biostimulant. A biofungicide is a biological control agent that kills or inhibits pathogenic fungi; and the compositions and formulations herein can, in some instances, be a biofungicide or a biological control agent, as described herein. Methods of using such compositions and formulations include delivering the formulation to a plant.

In some embodiments, an effective amount is intended to mean an amount of a formulation described herein sufficient to inhibit the growth of a microorganism on a plant by, for example, 10%, 20%, 50%, 75%, 80%, 90%, 95%, or more; or 1-fold, 3-fold, 5- fold, 10-fold, 20-fold, or more, as compared to a negative control plant not treated with a formulation or a composition provided herein.
[0041] As used herein, an “isolate” means a separated or isolated culture that includes a microorganism, as well as a portion of such a culture. Non- limiting microorganisms include a bacteria, a virus, or a fungus, as well as particular species for such microorganisms.

The isolate can include components from the same microorganism, from different species of a microorganism, or from different microorganisms. As described herein, a non-limiting example of an isolate includes a Trichoderma isolate. Such a Trichoderma isolate can include one or more components obtained from a culture including one or more Trichoderma species; or obtained by combining components from two or more cultures, in which at least one culture includes one or more Trichoderma species.
[0042] The terms “polynucleotide” and “nucleic acid,” used interchangeably herein, refer to a polymeric form of nucleotides of any length, either ribonucleotides or deoxyribonucleotides.Thus, this term includes, but is not limited to, single-stranded (e.g., sense or antisense), doublestranded, or multi-stranded ribonucleic acids (RNAs), deoxyribonucleic acids (DNAs), threose nucleic acids (TNAs), glycol nucleic acids (GNAs), peptide nucleic acids (PNAs), locked nucleic acids (LNAs), or hybrids thereof, genomic DNA, cDNA, DNA-RNA hybrids, or a polymer comprising purine and pyrimidine bases or other natural, chemically or biochemically modified, non-natural, or derivatized nucleotide bases. Polynucleotides can have any useful two- dimensional or three-dimensional structure or motif, such as regions including one or more duplex, triplex, quadruplex, hairpin, and / or pseudoknot structures or motifs.
[0043] As used herein, when a polypeptide or nucleic acid sequence is referred to as having “at least X % sequence identity” to a reference sequence, it is meant that at least X percent of the amino acids or nucleotides in the polypeptide or nucleic acid are identical to those of the reference sequence when the sequences are optimally aligned. An optimal alignment of sequences can be determined in various ways that are within the skill in the art, for instance, the Smith Waterman alignment algorithm (Smith TF et al., J. Mol. Biol. 1981; 147:195-7) and BLAST (Basic Local Alignment Search Tool; Altschul SF et al., J. Mol. Biol. 1990; 215:403- 10). These and other alignment algorithms are accessible using publicly available computer software such as “Best Fit” (Smith TF et al., Adv. Appl. Math. 1981; 2(4):482-9) as incorporated into GeneMatcher Plus.TM. (Schwarz and Dayhof, “Atlas of Protein Sequence and Structure,” ed. Dayhoff, M. O., pp. 353-358, 1979), BLAST, BLAST-2, BLAST-P, BLAST-N, BLAST-X, WU-BLAST-2, ALIGN, ALIGN-2, CLUSTAL, T-COFFEE, MUSCLE, MAFFT, or Megalign (DNASTAR). In addition, those skilled in the art can determine appropriate parameters for measuring alignment, including any algorithms needed to achieve optimal alignment over the length of the sequences being compared. In general, for polypeptides, the length of comparison sequences can be at least five amino acids, preferably 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 175, 200, 250, 300, 400, 500, 600, 700, or more amino acids, up to the entire length of the polypeptide. For nucleic acids, the length of comparison sequences can generally be at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 175, 200, 250, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, or more nucleotides, up to the entire length of the nucleic acid molecule. It is understood that for the purposes of determining sequence identity when comparing a DNA sequence to an RNA sequence, a thymine nucleotide is equivalent to an uracil nucleotide.
[0044] By ‘ ‘substantial identity” or “substantially identical” is meant a polypeptide or nucleic acid sequence that has the same polypeptide or nucleic acid sequence, respectively, as a reference sequence, or has a specified percentage of amino acid residues or nucleotides,respectively, that are the same at the corresponding location within a reference sequence when the two sequences are optimally aligned. For example, an amino acid sequence that is “substantially identical” to a reference sequence has at least about 50%, 60%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% sequence identity to the reference amino acid sequence. For polypeptides, the length of comparison sequences will generally be at least 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 50, 75, 90, 100, 150, 200, 250, 300, or 350 contiguous amino acids (e.g., a full-length sequence). For nucleic acids, the length of comparison sequences will generally be at least 5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 contiguous nucleotides (e.g., the full-length nucleotide sequence). Sequence identity may be measured using sequence analysis software on the default setting (e.g., Sequence Analysis Software Package of the Genetics Computer Group, University of Wisconsin Biotechnology Center, 1710 University Avenue, Madison, Wis., 53705). Such software may match similar sequences by assigning degrees of homology to various substitutions, deletions, and other modifications. The present disclosure encompasses a polypeptide or nucleic acid sequence that is substantially identical to any described herein.
[0045] By ‘ ‘protein,” “peptide,” or “polypeptide,” as used interchangeably, is meant any chain of more than two amino acids, regardless of post-translational modification (e.g., glycosylation or phosphorylation), constituting all or part of a naturally occurring polypeptide or peptide, or constituting a non-naturally occurring polypeptide or peptide, which can include coded amino acids, non-coded amino acids, modified amino acids (e.g., chemically and / or biologically modified amino acids), and / or modified backbones. Non-limiting amino acids include glycine (Gly, G), alanine (Ala, A), valine (Vai, V), isoleucine (He, I), leucine (Leu, L), cysteine (Cys, C), methionine (Met, M), aspartic acid (Asp, D), glutamic acid (Glu, E), arginine (Arg, R), histidine (His, H), lysine (Lys, K), asparagine (Asn, N), glutamine (Gin, Q), serine (Ser, S), threonine (Thr, T), proline (Pro, P), phenylalanine (Phe, F), tyrosine (Tyr, Y), tryptophan (Trp, W), selenocysteine (Sec, U), and pyrrolysine (Pyl, O).
[0046] A “peptide” may refer to a linear chain of amino acids linked by amide-type chemical bonds, which are called peptide bonds. Thus, to form peptides, amino acids are linked together forming chains of variable length and sequence. Dipeptides may refer to a linear chain of two amino acids linked by a peptide bond. Tripeptides may refer to a linear chain of three amino acids, and tetrapeptides may refer to a linear chain of four amino acids.
[0047] An “oligopeptide” may refer to a peptide having less than 10 amino acids.
[0048] The term “modified,” as used in reference to amino acids, means an amino acid including one or more modifications, such as a post-translation modification (e.g., acetylation,methylation, phosphorylation, ubiquitination, sumoylation, ribosylation, glycosylation, acylation, or isomerization), or including a non-natural amino acid.
[0049] The term “modified,” as used in reference to a protein, means a polypeptide sequence including one or more amino acid substitution, as compared to the reference sequence for the protein.
[0050] The term “fragment” is meant a portion of a nucleic acid or a polypeptide that is at least one nucleotide or one amino acid shorter than the reference sequence. This portion contains, preferably, at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or 90% of the entire length of the reference nucleic acid molecule or polypeptide. A fragment may contain 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1250, 1500, 1750, 1800 or more nucleotides; or 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 640 amino acids or more. In another example, any polypeptide fragment can include a stretch of at least about 5 (e.g., about 10, about 20, about 30, about 40, about 50, or about 100) amino acids that are at least about 40% (e.g., about 50%, about 60%, about 70%, about 80%, about 90%, about 95%, about 87%, about 98%, about 99%, or about 100%) identical to any of the sequences described herein can be utilized in accordance with the invention. In certain embodiments, a polypeptide to be utilized in accordance with the invention includes 2, 3, 4, 5, 6, 7, 8, 9, 10, or more mutations (e.g., one or more conservative amino acid substitutions, as described herein). In yet another example, any nucleic acid fragment can include a stretch of at least about 5 (e.g., about 7, about 8, about 10, about 12, about 14, about 18, about 20, about 24, about 28, about 30, or more) nucleotides that are at least about 40% (about 50%, about 60%, about 70%, about 80%, about 90%, about 95%, about 87%, about 98%, about 99%, or about 100%) identical to any of the sequences described herein can be utilized in accordance with the invention.
[0051] The term “conservative amino acid substitution” refers to the interchangeability in proteins of amino acid residues having similar side chains (e.g., of similar size, charge, and / or polarity). For example, a group of amino acids having aliphatic side chains consists of glycine (Gly, G), alanine (Ala, A), valine (Vai, V), leucine (Leu, L), and isoleucine (He, I); a group of amino acids having aliphatic-hydroxyl side chains consists of serine (Ser, S) and threonine (Thr, T); a group of amino acids having amide containing side chains consisting of asparagine (Asn, N) and glutamine (Gin, Q); a group of amino acids having aromatic side chains consists of phenylalanine (Phe, F), tyrosine (Tyr, Y), and tryptophan (Trp, W); a group of amino acids having basic side chains consists of lysine (Lys, K), arginine (Arg, R), and histidine (His, H); a group of amino acids having acidic side chains consists of glutamic acid (Glu, E) and aspartic acid (Asp, D); a group of polar amino acids consists of D, E, N, and Q; and a group of aminoacids having sulfur containing side chains consists of cysteine (Cys, C) and methionine (Met, M). Exemplary conservative amino acid substitution groups are valine-leucine-isoleucine (VLI), phenylalanine-tyrosine (FY), lysine-arginine (KR), alanine-valine (AV), glycine- serine (GS), glutamate- aspartate (ED), and asparagine-glutamine (NQ).

[0065] In the following description, numerous specific details are set forth to provide a thorough understanding of the presented embodiments. The disclosed embodiments may be practiced without some or all of these specific details. In other instances, well-known process operations have not been described in detail to not unnecessarily obscure the disclosed embodiments. While the disclosed embodiments will be described in conjunction with the specific embodiments, it will be understood that it is not intended to limit the disclosed embodiments.
[0066] Agricultural crop generation involves consideration of various factors to ensure healthy and productive growth of the crops, including the geographical location and growth conditions. However, crops may encounter various agricultural growth difficulties, including soil contamination, genetic mutations, pests (such as insects), disease (e.g., fungal, bacterial, and viral diseases), disruptive effects of automated techniques (e.g., tilling, planting, harvesting, watering, etc.), and other non- ideal growing conditions such as soil composition, humidity (excessive or very low), temperature (very high or very low), luminosity level (e.g., excess solar luminosity or lack thereof), flooding and / or drought, stress caused by fertilizers, inadequate pollination, excess of soil salts (e.g., minerals), and lack of organic material and / or minerals in the soil.
[0067] In one embodiment, it is useful to use substances that act as a biological control agent (BCA). For instance, such an agent can counteract the growth or effect of pathogenic microbes on a plant or a plant material. In one example, a BCA includes a biofungicide that kills or inhibits pathogenic fungi. A BCA can also exhibit other properties, such as for a biostimulant that stimulates plant growth.
[0068] In another embodiment, to help resolve agricultural growth difficulties, it is useful to use substances that are compatible with the plants. One type of compatibility that may be used considers the types of amino acids that the plant generates to sustain life. During the agricultural growth process, plants spend energy manufacturing certain amino acids that are important for their well-being. Biostimulants and / or nutritional correctors can supply these amino acids and allow the plant to redirect its energy to performing other functions. Application of biostimulants may reduce negative impacts of biotic stressors as well as abiotic stressors and help correct micronutrient and / or macronutrient deficiencies in the plant. Biostimulant compositions described herein have an amino acid profile. That profile may be based, at least in part, on an initial feedstock used to make the biostimulant composition. Example feedstocks include plant waste (e.g., husks or seedpods) and plants having limited economic value.
[0069] It has been observed that some biostimulant compositions, such as those derived from rice, do not have an amino acid profile that matches the needs of some plants growing under some conditions. Additionally, some biostimulant compositions are created using acid hydrolysis, which often destroys certain nutrients and / or amino acids in the feedstock, which can generate free amino acids that may be useful to a plant. While animal derived biostimulants may be generated, such biostimulant compositions lack some components such as phytohormones that are beneficial for plant growth. Further, it is generally more difficult to break down proteins from animal feedstock than from plant feedstock. Some biostimulant compositions may also not be suitable because of synthesis difficulties, lack of efficiency in generating the composition, cost of production, and environmental condition limitations.
[0070] Preparing such biofungicides or biostimulants can be challenging, and this present disclosure relates to proteases from one or more Trichoderma species for enzymatic hydrolysis of the feedstock. In particular, the protease can be provided in a formulation (e.g., a protease formulation) configured to hydrolyze a plant protein or a feedstock including the plant protein. The protease can be isolated from a Trichoderma species prior to being introduced to the feedstock. Alternatively, an isolate including the Trichoderma species can be provided to the feedstock, so long as the isolate provides or expresses the desired protease.
[0071] In certain embodiments, the feedstock contains plant material such material from a carob plant, a peanut plant, a lupin plant, a soybean plant, a rice plant, or the like. Sources that have a high concentration of vegetable protein can be used in various embodiments. When biostimulant compositions or biofungicidal compositions are produced from plant feedstock, acid hydrolysis is not used. Some disclosed biostimulant compositions are produced by enzymatic hydrolysis of plant feedstock.
[0072] The protease can be used to enzymatically treat the feedstock, thereby providing a hydrolysis product. The protease may be provided as a formulation, which can include any useful carrier or additive, such as any described herein. For example, the protease (or mixture of proteases) may be provided in liquid form or solid form (e.g., lyophilized form). In use, the protease formulation can be added to the feedstock and then incubated under conditions to promote proteolytic cleavage of plant proteins present within the feedstock, thereby providing a liquid-based hydrolysis product.
[0073] The hydrolysis product can include multiple amino acids, in one instance. Other components may be present, such as one or more components that act as a secondary metabolite. Certain disclosed biostimulant compositions can include oligopeptides that may bioencapsulatemicronutrients and / or macronutrients. In certain embodiments, biostimulant compositions are produced from feedstocks that generate an amino acid profile suitable for plants of many types.
[0074] The result from enzymatic hydrolysis of feedstock may include free amino acids, peptides, and proteins. Free amino acids can be obtained from hydrolysis and are not bound to any other amino acids through peptide bonds. Due to the low molecular weight of free amino acids, plants are able to assimilate free amino acids quickly and their effects on plant metabolism are more defined. Therefore, free amino acids can be important in plant nutrition. Of note, when two or more amino acids are joined together (by a peptic bond), they form a peptide. The longer the length of the peptide (more amino acids attached), the more difficult will be the direct assimilation by plants. In addition to free amino acids, peptides or proteins may be present within the liquid hydrolysis product. The union of the different polypeptide chains forms a protein. The structural units of proteins are the amino acids joined in a sequence and the characteristic order for each type of protein. Free amino acids and some low molecular weight peptides are useful as products applied to plants. The percentage of each type of amino acids depends on the type of hydrolysate and the origin of the proteins (animal or vegetable), and with it, the quality of the final product.
[0075] FIG. 1A shows a non-limiting schematic illustration of components within a hydrolysis product. Provided is a composition 100 having a liquid 110 with suspended components. The suspended components include various types of free amino acids, which are depicted as a first type of amino acid 120a and a second type of amino acid 120b. Although two types are depicted in this figure, it will be understood by a person of skill in the art that many types of free amino acids may be in the liquid 110 depending on the amino acid profile, and that the relative concentrations of the free amino acids may vary. The liquid 110 can also include oligopeptides 130, in which enzymatic treatment may not completely hydrolyze the entire protein into fee amino acids.
[0076] The hydrolysis product, in turn, can be employed as a biostimulant composition and can include other additives (e.g., nutrients) to provide a formulation (e.g., a biostimulant formulation). Such formulations can stimulate plant growth, such as for a biostimulant. In other instances, the compositions and formulations herein can provide biotic stress relief, in which, for example, the plant might be capable of continuing production even when under attack by a pathogen.
[0077] For instance, FIG. IB shows an example of a biostimulant formulation or a biofungicidal formulation including various components. FIG. IB includes a formulation 101 having a liquid 111 with suspended components. The suspended components include varioustypes of free amino acids, which are depicted as a first type of amino acid 120a and a second type of amino acid 120b. As described above, many types of free amino acids may be in the liquid depending on the amino acid profile, and the relative concentrations of the free amino acids may vary. The liquid 111 also includes macronutrients 140, as well as micronutrients 150a / 150b / 150c. Although one type of macronutrient and three types of micronutrients are depicted in this figure, it will be understood by a person of skill in the art that more or fewer types of micronutrients and more or fewer types of macronutrients may be presented in the composition 101.
[0078] In various embodiments, manganese, boron, zinc, and mixtures of zinc and manganese may be one or more of micronutrients 150a / 150b / 150c. In some embodiments, only one type of micronutrient (e.g., manganese, boron, or zinc) is present. In some embodiments, mixtures of micronutrients (e.g., zinc and manganese) are present. In various embodiments, calcium or potassium may be macronutrient 140. In some embodiment, only one type of macronutrient is added; and no additional micronutrients 150a / 150b / 150c are added, but some micronutrients from the original feedstock itself may be present. In some embodiments, some micronutrients 150a / 150b / 150c and / or macronutrients 140 may be derived from the plant-based protein source. In some embodiments, some micronutrients 150a / 150b / 150c and / or macronutrients 140 may be subsequently added to the liquid 111. The liquid 111 can also include oligopeptides 130, which may bioencapsulate micronutrients 150a / 150b / 150c to help facilitate their delivery to parts of a plant.
[0079] The compositions and formulations herein can be prepared by providing a feedstock and then combining one or more proteases from a Trichoderma strains or species with the feedstock, thereby obtaining a hydrolysis product. The hydrolysis product may be further treated, such as by separating one or more components from the hydrolysis product and optionally combining the component(s) with a nutrient.
[0080] The compositions and formulations herein can be prepared using any of various methods. In some embodiments, the compositions are made by conducting enzymatic hydrolysis of a plant-based protein source and by optionally adding supplemental nutrients to the composition, either before or after the hydrolysis. The enzymatic hydrolysis converts plantbased protein to free amino acids and oligopeptides.
[0081] FIG. 2A provides a process flow diagram depicting operations of a method embodiment described herein. In an operation 210, a plant protein and / or feedstock is provided. Example plant sources of feedstock, including plant-based proteins, are described herein and may include but are not limited to carobs, peanuts, rice, soybean, Plukenetia volubilis, and tarwi.The raw plant-based feedstock may be processed (such as ground to a meal), to achieve a feedstock with a particular particle size and water content. In some embodiments, the plantbased feedstock is dried and then milled.
[0082] Yet other plant-based protein sources include but are not limited to plant material from the Fabaceae and / or Leguminosae family. Particular examples of plant-based protein sources include plant material from the Cer atonia genus, the Arachis genus, the Lupinus genus, the Glycine genus and the Pisum genus. For example, carob germ or carobs (Ce rat onia siliqua) may be a suitable plant-based protein source. Peanuts (Arachis hypogaea) may also be a suitable plant-based protein source. Tarwi (Lupinus mutahilis) may also be a suitable plant-based protein source. Soybean (Glycine max) may also be a suitable plant-based protein source. Peas (Pisum sativum) may also be a suitable plant-based protein source. Other suitable genera that may provide a protein source include but are not limited to Astragalus, Acacia, Indigofera, Crotalaria, and Mimosa.
[0083] Some plant-based protein sources may be from the Euphorbiaceae family. An example genus from this family is the Plukenetia genus. Plukenetia volubilis, or sacha inchi, is a perennial plant that is native to tropical South America. Plukenetia volubilis may also be a suitable plant-based protein source as it may have significant protein content as well as omega-3 fatty acids, omega-6 fatty acids, and omega-9 fatty acids. Other plant-based protein sources may be from the Poaceae family. One example genus from this family is the Oryza genus. For example, rice may be a suitable plant-based protein source.
[0084] In various embodiments, parts of a plant may be used as the plant-based protein source. Example sources include but are not limited to roots, stems, husks, leaves, and seeds. In certain embodiments, plant feedstock is used with little or no preparation other than harvesting and optionally storing and / or milling. In some embodiments, plant feedstock is subject to a postharvest process such as high temperature drying, oil extraction, or similar process. In peanut sources, after oil extraction, the remaining dry “cake” is used as feedstock. In carob sources, the whole seed with the husk is dried and milled to form the feedstock. In lupine sources, the beans are dried and milled to form the feedstock.
[0085] In some embodiments, the plant-based protein source may have at least about 60% protein content by weight of the prepared feedstock (such as dry cake of peanut feedstock), or at least about 50% protein content by weight, or at least about 30% protein content by weight.
[0086] Turning back to FIG. 2A, an optional operation 212 can include pre-processing the feedstock (such as a feedstock powder. Pre-processing may be performed to eliminate polyphenols in vegetable flour because they inhibit the functioning of protease enzymes.Various types of pre-hydrolysis may be performed. Examples include mechanical agitation, addition of water or other liquid, chemical processing such as chemical extraction, sieving, etc. In one example, during pre-hydrolysis processing, polyphenols are extracted from the meal or other feedstock using, e.g., ethanol. In another instance, the feedstock can be sterilized.
[0087] Proteases may be mixed with the plant-based feedstock powder. The pH may also be adjusted to make the pH suitable for the enzyme used. In some embodiments, enzymes for conducting enzymatic hydrolysis are added to the feedstock during a preprocessing operation. In an operation 220, the feedstock is introduced to an enzymatic hydrolysis reactor.
[0088] An example of a hydrolysis reactor is provided in FIG. 5. The enzymatic hydrolysis reactor may include a vessel 504 for containing and / or mixing various components, including processed feedstock and enzymes from a source 502 through inlet 503. In some embodiments, the enzymatic hydrolysis reactor includes a mixing or agitation mechanism such as propeller 505. The reactor also includes a pH probe 510 for measuring pH. pH and temperature are controlled in the vessel 504. The pH may be maintained at any useful pH range, depending on the type of protease employed in the reactor. In one instance, the pH range is between 7 and 9, or about 8.5. The pH can be controlled by including an inlet 509 for dripping acid or base fluids to regulate the pH. For example, 10 M of NaOH may be added to maintain a pH of about 8.5.
[0089] The temperature may be maintained at a temperature between about 55 °C and about 60°C. The temperature may be maintained by using heat sleeve 508, a heater, and / or a chiller. The enzymatic hydrolysis reactor can be configured to hydrolyze proteins in the feedstock to produce free amino acids and oligopeptides. Proteases can be added to the feedstock either before or after the feedstock is introduced to the reactor. Water may be added to the enzymes and / or feedstock, either before or after the feedstock is introduced to the reactor. Once, all the components are added to the reactor, the temperature and / or pressure of the reactor may be adjusted and, from there, enzymatic hydrolysis can proceed. In some embodiments, the plantbased feedstock includes enzymes, plant-based protein source as a powder, and water.
[0090] The type of enzyme used in enzymatic hydrolysis depends on the feedstock and the type of amino acid profile desired for the biostimulant composition. Enzymes are capable of breaking protein chains at a particular hydrolysis reaction rate. One enzyme that may be used is a protease that is a purified liquid enzymatic preparation. Some enzymes are widely available and widely used in the detergent production industry, the food industry, and in the textile industry. Examples of proteases that may be used for enzymatic hydrolysis include but are not limited to aspartic proteases, serine proteases, thiol proteases, metalloproteases, as well as any others described herein (e.g., in Tables 1-5 or FIGs. 7-13). Examples of aspartic proteasesinclude but are not limited to pepsin, pepsin A, chymosin, and renin. Examples of serine proteases include but are not limited to trypsin, chymotrypsin, subtilisin novo, and alcalase. Examples of thiol proteases include but are not limited to pure papain and bromelain. Proteases may be derived from one or more of the following sources: ox, pig, calf, papaya, pineapple, Bacillus subtilis, Bacillus lichiniformis, Aspergillus niger, Ananas comosus, and Aspergillus oryzae. Proteases may be provided as a mixture of various types of proteases. For example, a protease that is provided for enzymatic hydrolysis may include a mix of an aspartic protease, a metalloprotease, and a serine protease. Examples of protease mixtures include but are not limited to ProZyme™ available from PRN Pharmacal in Pensacola, FL; Panzyme™ available from Nutra BioGenesis in Park City, Utah Biozyme A™ available from G-Biosciences in St. Louis, MO, and Sanzyme available from Ciba Giegy of Switzerland.
[0091] Returning to FIG. 2A, in an operation 222, enzymatic hydrolysis is performed. During enzymatic hydrolysis, the following parameters can be monitored and controlled: substrate and enzyme concentration, reaction temperature, pH, and stirring speed. The reference substrate (e.g., vegetable flour) concentration of milled feedstock weight to water volume can be about 10% to 15% (w / v).
[0092] In one example, for enzymatic hydrolysis of carob germ, water is added to 300 grams of carob germ having a dry matter content of 55% to a final volume of 1 L, such that the resulting mixtures includes a concentration of protein content of 18% (w / v). The enzyme concentration during enzymatic hydrolysis may be about 0.1% to 0.2% (v / v) or about 0.15 % (v / v). Enzymatic hydrolysis may be performed in the reactor at a temperature of about 45 °C to 55°C or up to 60°C. In some embodiments, the mixture may be mixed for a duration of about 2 hours to 4 hours. The enzymatic hydrolysis may be performed at standard atmospheric pressure.
[0093] The pH of the enzymatic hydrolysis is determined by the pH suitable for the protease selected. Some enzymes are suitable for a pH of about 7 to 11, and some can have maximum activity at a pH of about 9. During enzymatic hydrolysis, concentrated NaOH may be added to maintain the pH in such way so as not to substantially increase the volume in the vessel.
[0094] Stirring speed may be adjusted throughout the enzymatic hydrolysis process depending on the texture of the hydrolysates. For example, when insoluble material solubilizes, stirring speed may be reduced to accommodate the newly soluble texture of the hydrolysates. Enzymatic hydrolysis may be performed until about 10% by weight or at least about 50% by weight of the amount of proteins in the feedstock is left unconverted to free amino acids, oligopeptides, and peptides.
[0095] After the hydrolysis process completes, the hydrolysis product may be optionally centrifuged. The centrifuged hydrolyzed mixture is removed from the reactor which may be performed by delivering via an outlet 506 of FIG. 5 to a filter 507. While proteinaceous material in the feedstock is broken down by proteases, other material in the feedstock is left wholly or partially unreacted. Examples of such unreacted materials include, micronutrients, macronutrients, phytohormones, and the secondary metabolites. Such unreacted material can include solid waste products, which can be separated by centrifugation, filtered, or otherwise removed and then discarded.
[0096] The hydrolysis product can be employed as a biostimulant composition or a biofungicidal composition. Alternatively, further operations can be conducted to further isolate, treat, or modify the hydrolysis product to provide a formulation. In some embodiments, after hydrolysis, hydrolyzing enzymes are inactivated by, e.g., a temperature shock. As seen in FIG. 2B, in an operation 230, the products from the enzymatic hydrolysis can be filtered. In some embodiments, two filtrations are carried out (coarse and fine). The first filtration eliminates solids, and the second eliminates further contaminants and solids, which are smaller in size. After filtration, in certain embodiments, the product is concentrated to a density of about 1 to 1.3 g / mL, such as about 1.18 g / mL. Finally, in some embodiments, the resulting product is pasteurized to eliminate microorganism contaminants.
[0097] In an operation 240, the biostimulant composition or the biofungicidal composition can be diluted to an amount, such as those described above. In some embodiments, water is added to the composition to achieve a water content of at least about 40% by volume.
[0098] In an operation 250, nutrients such as micronutrients and / or macronutrients are added to the filtered and diluted products to generate a biostimulant formulation. The micronutrients and macronutrients can be mixed with the products from the reactor to form a homogeneous mixture, which may prevent particles from sinking to the bottom of the liquid. Mixing may be performed using a paddle or other mechanical component, which may be automatically or manually controlled. Micronutrients include but are not limited to iron, manganese, boron, molybdenum, zinc, chlorine, sodium, and cobalt. One, two, three, or more of the above micronutrients may be added. The amount added may be such that they result in the concentration of each micronutrient including both added micronutrients and existing micronutrients from the plant-based protein source, in the biostimulant composition to be of about 1% to 15% by weight.
[0099] Macronutrients include nitrogen, phosphorous, potassium, calcium, sulfur, magnesium, carbon, oxygen, and hydrogen, which may also be added such that the resultingconcentration of one or more of the macronutrients is about 1% to 15% by weight. In some embodiments, macronutrients are not added.
[0100] In an operation 260, the diluted composition can be packaged. As described above, the diluted composition may be packaged in liquid form into containers (e.g., bottles) of any of various sizes, such as IL bottles.
[0101] In some embodiments, the methods herein allow for enzymatic processing of feedstock that are generally deemed to be of low value or of low accessibility. For instance, some feedstocks that may be used have organic origin that have traditionally been considered directly as waste, or at most, are considered low added value materials. These different agroindustrial by-products have properties that give them great potential for application in the agricultural biotechnology industry. In another instance, these starting materials are not easily usable, as they are not accessible or available. For example, its high insolubility, mainly, makes its use difficult. However, enzyme technology, with extraction and / or modification processes, can convert these organic materials into new products with greater functionality, due to the concentration of active principles, and better application technological properties (increased solubility and decreased molecular size of its components).
[0102] The compositions and formulations described herein can be applied to crops or plants in various ways. Methods of using the composition and formulation can include treating a plant, such as by preparing any composition or a formulation herein; and delivering the composition or the formulation to a plant, a portion thereof, a plant material, or a soil in proximity to the plant. The composition or the formulation can be a biostimulant, a biofungicide, and / or a BCA. In one embodiment, the formulation includes the composition and another component, such as an added aqueous solvent (e.g., water). Such methods can be useful for, in some instances, in preventative treatment of plants or plant materials.
[0103] The compositions and formulations herein can be applied or delivered to a plant in any useful manner. Delivering can include any useful method, such as by providing the composition or formulation by way of fertigation delivery to an irrigation system (e.g., a drip irrigation system), or by way of foliar delivery directly to plants. In one embodiment, the composition or formulation can be applied by dissolving in an aqueous solvent prior to delivery to the soil, the plant, or the plant material (e.g., seed, seedling, bulb, etc.). In another embodiment, application can include pilling the seeds of a plant (e.g., using any coating described herein). In yet another embodiment, application can include immersion of the plant or the plant material in a bath containing a composition or formulation herein. Furthermore, application can include providing one or more additives (e.g., any herein) before, during, or afterdelivery of the composition or formulation to the soil, the plant, or the plant material. Other modes of delivery include broadcast application, liquid or dry in-furrow application, spraying, atomizing, vaporizing, misting, scattering, dusting, coating, watering, squirting, sprinkling, pouring, fumigating, and the like to the locus to be protected.
[0104] In particular embodiments, delivery can result in treating a plant. Such treating can include protecting the plant against a pathogenic organism, stimulating growth of the plant, or counteracting growth of a pathogenic organism in proximity to the plant. Use can include delivering an effective amount of the composition or formulation onto the soil and / or on the plants for such treatment. Such delivery can include drip irrigation (e.g., at or close to transplanting, with optional delivery at a later interval after 14-30 days), spraying (e.g., directed either in furrow during planting or to the soil surface after planting), soaking (e.g., soaking of soil; and / or soaking of plants or plant materials prior to planting), soil treatment (before or after sowing or transplanting), direct mixing with soil, direct application to seeds, and the like. Such treatment can provide, for instance, better root development, increased proliferation of secondary roots, increased seedling weight, and / or improved crop yields.
[0105] Delivery or treatment can include any useful regime. In one instance, delivery includes providing the composition or formulation at or close to transplanting. In another instance, delivery can include application at one or more stages of plant growth (e.g., germination, flowering, fruiting, etc.). Application can include one or more locations on the plant or soil (e.g., stem, leaves, roots, flowers, and / or fruit). Such application can include multiple applications to a single plant at different times (e.g., at or close to transplanting, with optional delivery at a later interval after 14-30 days).
[0106] Prior to applying to crops, a biostimulant composition can be diluted. FIG. 3 provides a process flow diagram depicting operations that may be performed in accordance with certain embodiments. In operation 310, the plant to be treated is located or provided. The plant can be any one of a variety of crops, both ones having intensive short cycles and extensive long cycles. Examples include but are not limited to vegetables, industrial grains, berries, sugar cane, fruit trees, superfoods, and grapes. Biostimulants are not crop specific and can be useful for the vast majority of crops grown, including agricultural, medical and horticultural crops. They can be used in organic or conventional farming. Each plant type can utilize a different application regime of biostimulant, to maximize productivity.
[0107] In operation 315, a biostimulant is diluted to an amount such as those described above. In some embodiments, water is added to the biostimulant composition to achieve a water content of at least about 40% by volume.
[0108] In operation 320, the diluted biostimulant is applied to a target crop. When the diluted biostimulant is applied depends on the composition of the biostimulant, the amount of diluted biostimulant applied, and the time in the life cycle of the plant that can take advantage of the benefits of the biostimulant composition. Plants undergo various stages of life in their life cycles: seeds, sprouts or germination, seedlings, adult plants that undergo pre-flowering, flowering, pre-fruiting, and / or fruiting. Plants undergo reproduction and pollination, which may involve growth of flowers and / or fruits, prior to seed spreading. Some plants in different parts of their life cycles can use different amounts of a diluted biostimulant. Some plants in different parts of their life cycles can use different amounts of the same biostimulant. Biostimulant compositions can be applied to various parts of a plant, such as the seed, seedling, stem, leaves, branches, flowers, and fruit, and its surroundings, including the soil. The diluted biostimulant may be applied to a plant in a pot, or a plant grown by hydroponics, or a plant grown in an open field. Each of these types of plants may utilize different amounts of biostimulant.
[0109] The location in which the diluted biostimulant is applied may also vary from plant to plant. For example, in some embodiments, irrigation systems are used, such as shown in the example in FIG. 4A, which includes a schematic diagram of a plant 401 having roots 403 in soil 402 under a light source 404 (in this case, the sun). Also provided is an irrigation system having piping 406 and a delivery spout 405, whereby the trajectory 408a of a diluted biostimulant may be used to apply the diluted biostimulant via irrigation.
[0110] In some embodiments, diluted biostimulants are applied directly to a plant, such as to the leaves or the foliage of a plant and may be manually applied by a person. An example is provided in FIG. 4B, which is a schematic diagram of a plant 401 having roots 403 in soil 402 under a light source 404, whereby the trajectory 408b of a diluted biostimulant is delivered or sprayed via a mister 412 handled by a human 410 from a container 411 of biostimulant. Where the diluted biostimulant is applied depends on environmental variables as well.
[0111] Any of the discussions herein regarding the diluted biostimulant could be used to form and deliver a diluted biofungicide. For instance, the timing of application and amount of a dilute biofungicide could depend on the plant life cycle, environmental variables, and the like.
[0112] The compositions or formulations herein can be employed in any useful plant, portion thereof (e.g., roots, tubers, stems, flowers, and / or leaves), plant material (e.g., seed, seedlings, bulbs, etc.), or soil for growing such plants. Non-limiting plants include crop plants, turfs, ornamentals, agronomic row or other field crops, plants prone to fungal contamination (e.g., tomatoes, bell peppers, soy, and the like), and plants prone to new pathogenic fungi (e.g., rice,wheat, and the like). Yet other plants include agricultural plant species, including coffee, cucumber, tomato, pepper, and radish.
[0113] In some embodiments, the compositions and formulations herein can be used against pathogens, including pathogenic fungi. Non-limiting pathogens include Botryosphaeria (e.g., B. dothidea), Botrytis (e.g., B. cinere ), Clarireedia (e.g., C. homoeocarpa), Colletotrichum (e.g., C. coccodes), Fusarium (e.g., F. oxysporum), Macrophomina (e.g., M. phaseolina), Phytophthora (e.g., P. cactorum, P. cinnamomi, P. citricola, P. citrophthora, P. cryptogea, P. drechsleri, P. infestans, and / or P. nicotianae), Pythium (e.g., P. aphanidermatum, P. irregulare, P. spiculum, and / or P. ultimum), Rhizoctonia (e.g., R. solani), Rosellinia (e.g., R. necatrix), Sclerotinia (e.g., S. homoeocarpa, S. sclerotiorum, and / or S. solfsii), Sclerotium (e.g., S. rolfsii), Thielaviopsis (e.g., T. basicola) species, Verticillium (e.g., V. dahliae), as well as combinations thereof.Proteases from Trichoderma and formulations thereof
[0114] One or more proteases may be employed to treat a feedstock. In some embodiments, the protease(s) can be from at least one particular Trichoderma species.

In some cases, the species is selected from Trichoderma parareesei, Trichoderma virens, Trichoderma atroviride, and Trichoderma asperellum. The protease can be provided as isolated proteins (e.g., isolated proteases) or as isolates, which can include spores, mycelium, or both.

Further Trichoderma species are described herein.
[0116] The relative amount of each protease from each species or strain can provide an effective amount to provide a particular effect. Such an effective amount can be determined by the amount that can provide a particular profile (e.g., amino acid profile) within the hydrolysis product.

[0140] Further proteases are provided below, including serine proteases (Table 1), aspartate proteases (Table 2), metalloproteases (Table 3), glutamate / glutamine proteases (Table 4), and cysteine proteases (Table 5) from a Trichoderma species.Table 1: Non-limiting serine proteases from TrichodermaTable 2: Non-limiting aspartate proteases from TrichodermaTable 3: Non-limiting metalloproteases from TrichodermaTable 4: Non-limiting glutamate / glutamine proteases from TrichodermaTable 5: Non-limiting cysteine proteases from Trichoderma
[0141] The proteases herein can be provided within a formulation (e.g., a protease formulation). This formulation, itself, can be employed as a reagent during hydrolysis processes or as a component within a biostimulant. The protease can be prepared in any useful manner.
[0142] In one instance, the protease can be isolated from an isolate obtained from a Trichoderma species, and the isolate can be obtained by fermentation. For instance, an initial inoculum having the Trichoderma strain may be maintained to provide a pure strain with minimal contaminants. In some embodiments, the initial inoculum is refreshed frequently and stored at 4°C. This initial inoculum can be grown on agar to provide the starting conidia (spores), which can then be washed from the surface of the culture with sterile saline and inoculated into culture media for fermentation (e.g., in a bioreactor).
[0143] In another instance, the fermentation broth is filtered to provide a filter cake, which can then be extruded to form granules. During extrusion and granulation, one or more carriers and / or additives can be added. Optionally, the filtrate (e.g., the protease) can be lyophilized and employed (e.g., in any formulation described herein).
[0144] In one embodiment, concentrated quantities of Trichoderma can be obtained using a liquid medium by inoculating pure Trichoderma species onto a solid agar plate (e.g., autoclaved potato dextrose agar (PDA)) for 1 week. Conidia (spores) can be washed from the surface of the culture with sterile saline and inoculated into semi-defined balanced media (SDBM, including molasses, urea, KH2PO4, MgSC -VFFO, and sodium citrate, pH of 7.0). Cultures can be grown at 28°C, shaking for 24 hours. The Trichoderma biomass can be filtered (e.g., through 100 pm sieves). Trichoderma produced in this way can, in some instances, possess more than 50% colonization potential through 10 days of storage. Studies have demonstrated, however, thatinclusion of additives, such as additional sugars or starches, metabolic inhibitors (such as CuSCh), or kaolin can increase the longevity of spore-containing cultures of fungus. Blended strains of Trichoderma with combinations of these additives can be prepared to assess the overall colonization potential both before and after four months of storage. In use, Trichoderma strains can be refreshed from time to time. In one instance, from a PDA plate with fresh and uncontaminated colonies, a pre-inoculum can be prepared for both liquid and solid formulations.
[0145] Any useful fermentation method can be used, such as liquid fermentation, semi-solid fermentation, solid fermentation, and biofilm formation. In one instance, fermentation can include fermentation with a culture medium including rice husk, sugar beet pulp, sugar cane bagasse, glucose, glucose nitrate, maltose, maltose peptone, hydrolyzed corn, molasses, dextrose, potato dextrose, soy, starch, whey, or other agricultural products or byproducts of the food industry in solid forms and / or broth forms. Prior to inoculation of the Trichoderma species, the culture medium can be sterilized.
[0146] Depending on the final formulation, strains may be grown at a temperature between about 24-25 °C. During the period of manufactory sporulation, the ecosystem can be controlled to avoid contamination from other fungi, such as penicillium. After sufficient production in the medium, the spores can be separated (e.g., centrifugation, air separation, filtration, etc.) and stored as active matter (e.g., such as in a solid formulation including the Trichoderma isolates). Alternatively, the liquid fermentation broth can be used as the active matter (e.g., such as in a liquid formulation including the Trichoderma isolates). In another embodiment, the fermentation broth can be filtered to provide a filter cake, which can then be processed to provide a solid formulation (e.g., granules, which can be obtained by granulation of the filter cake with one or more optional carriers and / or optional additives).
[0147] In some embodiments, a solid formulation of proteases from one or more Trichoderma species can be mixed with a solid carrier. If two or more species, are employed, then various ratios of the two proteases from each strain can be mixed with a solid carrier, as described herein.
[0148] Compositions and formulations can be tested in any useful manner, such as by using in vitro and in vivo assays. Non-limiting assays include enzymatic proteolytic assays, colony growth inhibition assays, conidial germination inhibition assays, viability assays, quantitative growth assessment of plant growth (e.g., as determined by plant height, number and / or quality of fruit, and the like), soil sample analysis (e.g., before, during, and after applying the formulation), total biomass measurements of plants, root growth determinations, and overall health monitoringof plants. In particular, in vitro assays can be conducted to test the enzymatic, proteolytic (or hydrolytic) activity of the protease for a detectable substrate.
[0149] Any of the protease compositions herein can be combined with a carrier to provide a formulation, which can be a liquid formulation, a solid formulation, or a semi-solid formulation. In some embodiments, a carrier is used with a Trichoderma or Trichoderma protease composition for hydrolyzing plant protein feedstock to produce a biostimulant formulation. Such carriers may be solid material (e.g., such as agar, particles, etc.) or a liquid (e.g., such as water or vegetable oil). The liquid carrier may also serve as a diluent.
[0150] In general, a carrier is an inert component within a formulation. While the presence of the inert ingredient may be helpful in using or delivering a formulation, the inert ingredient does not necessarily impart biofungicidal, biostimulant, or proteolytic effect. For instance, a protease formulation may include water or buffer as a carrier, which may assist in dispersing the protease into a feedstock to provide a liquid-based hydrolysis product; but the water and buffer itself does not provide bioactive effect.
[0151] A liquid formulation can include a liquid carrier, such as water, a vegetable oil, or a mineral oil. The liquid formulation can include any useful form, such as a concentrate (e.g., an emulsifiable concentrate) or an emulsion. In some embodiments, the liquid carrier is configured to stabilize formulation, thereby providing a shelf stable product. The liquid formulation can be processed to inactivate proteases. Inactivation processes can include use of thermal shock, exposure to light or radiation, and the like.
[0152] A solid formulation can include a solid particle. For example, the protease can be provided within a solid formulation. Note that whereas the protease formulation can be in liquid or solid form upon adding to a feedstock, the resulting hydrolysis product (e.g., as described herein) is typically in a liquid form. The solid particle can include a water-soluble, a wettable, or a water-dispersible particle, which can be dissolved or dispersed upon addition of an aqueous solvent. The particle can be of any form, such as a powder (e.g., a wettable powder, a freeze- dried powder, a spray-dried powder, a flowable powder, and the like), a pellet, or a granule (e.g., a microgranule, and the like). Such particles can be formed of a solid carrier such as a solid phase, a clay (e.g., kaolin), a sugar alcohol (e.g., sorbitol), a sugar, a saccharide, or a polysaccharide (e.g., cellulose). In another instance, the particle can be encapsulated with a coating, which can have one or more layers and in which each layer can include one or more solid carriers. Useful technologies and methodologies to prepare, synthesize, and modify nanoparticles can be employed to provide such coatings.
[0153] The concentration of the protease may depend on whether the formulation is a solid formulation or a liquid formulation. Within a solid formulation, the concentration of the protease(s) may be about 0.05 to 20 % (w / w) of a solid formulation.
[0154] The protease formulation can include one or more proteases from a Trichoderma species, and the remaining weight of the formulation can be one or more carriers (e.g., any described herein), which can optionally include any additives described herein. Non-limiting solid carriers include clays (e.g., kaolin), saccharides, polysaccharides (e.g., cellulose), and the like.
[0155] Within a liquid form of the protease formulation, the concentration of the protease(s) may be from about 0.1 to 100 % (w / v) or (v / v) of a liquid formulation. Such concentrations can be for each protease from each Trichoderma species within the formulation or for the combined concentration of all proteases from all Trichoderma species within the formulation. The remaining volume of the formulation can be one or more carriers (e.g., any described herein), which can optionally include any additives described herein. Non-limiting liquid carriers include mineral oil, water, and the like.
[0156] Carriers can include any useful combination of components, such as binders, encapsulating materials, carbonaceous matter, fillers, desiccants, liquids, dispersants, and the like. Non-limiting binders can include cellulose esters (e.g., methylcellulose and hydroxypropyl cellulose), organic silicates (e.g., organosilicon esters, gums, alginate, and the like), polyalkylene oxide (e.g., polyethylene oxide), polyvinyl alcohol, polyvinyl acetate, and starch.

[0159] Non-limiting fillers can include alginic acid, cellulose, chitin, clays, cyclodextrins, diatomaceous earths, dextrose granules or powders, gelatin, ground agricultural products, maltose-dextrose granules or powders, mineral powder (e.g., bentonite, cation clay, diatomaceous earth, kaolin, talc, and the like), porous beads or powders, porous wood products,silica, silicates, sucrose granules or powders, talc, vermiculite, zeolite, and combinations thereof. Such fillers may be useful, e.g., for improving seed coating and / or enhancing water absorption within the solid formulation.
[0160] Non- limiting desiccants include a sugar (e.g., a non-reducing sugar, a disaccharide, trehalose, sucrose, and the like), a polyol (e.g., glycerol, triethylene glycol, and the like), sugar alcohol (e.g., mannitol, sorbitol, and the like), calcium sulfate, silica, and combinations thereof.
[0161] Non-limiting liquids include water, buffer, oil (e.g., mineral oil, corn oil, olive oil, palm oil, palm kernel oil, peanut oil, rapeseed oil, rice bran oil, soybean oil, sunflower oil, vegetable oil, and the like), a non-aqueous solvent, an organic solvent (e.g., alcohol), polyethylene glycols (e.g., PEG 200, PEG 300, PEG 400, etc.),, propylene glycols (e.g., PPG-9, PPG-10, PPG-17, PPG-20, PPG-26, etc.), a polyethylene glycol-polypropylene glycol copolymer, an ethoxylated alcohol, an aqueous solvent (e.g., water or a buffer), polysorbates (e.g. polysorbate 20, polysorbate 40, polysorbate 60, polysorbate 80, etc.), silicones (siloxanes, trisiloxanes, etc.), and combinations thereof. Non-limiting dispersants include alcohol ethoxylates, naphthalene sulfonates, vinylpyrrolidone polymers, nonionic surfactants, ionic surfactants such as cationic or anionic surfactants, and the like.
[0162] Such formulations can further include one or more optional additives, such as any described herein. Additives can include added active ingredients, which may improve or enhance the formulation. For instance, such an additive can include zinc, manganese, and the like. For example, a protease may require the presence of a cofactor or a metal ion for maximal proteolytic activity, and the additive can include such a cofactor or metal ion.
[0163] Proteases from Trichoderma can be used to treat a feedstock and provide a biostimulant formulation. One non-limiting process is provided in FIG. 6, which includes an operation 610 for fermentation of Trichoderma within a culture. In operation 615, one or more components can be obtained from the culture. For instance, such components can include Trichoderma-d&n &d proteases and, optionally, viable Trichoderma and / or Trichoderma-denx'ed metabolites. Such Trichoderma-denx'ed components, or even viable Trichoderma itself, can be combined with feedstock 620. In one embodiment, an operation 630 includes enzymatic hydrolysis of the feedstock by using Trichoderma or Trichoderma-devw' ed components. For example, Trichoderma-d&d &d proteases can be used to lyse proteins present within the feedstock. During enzymatic hydrolysis, various process conditions can be optimized, such as temperature 632, pH 634, and the like.
[0164] Optionally, an operation 640 can be conducted to inactivate the proteases. Any useful inactivation method can be employed, such as use of thermal shock or radiation.
[0165] In operation 650, the resulting formulation or composition can be characterized as a biostimulant that can optionally include a fungicide. The biostimulant can include any described herein, such as a hydrolysis product or a component of a hydrolysis product (e.g., an amino acid and an oligopeptide, wherein the amino acid and the oligopeptide are derived from a plant-based feedstock). The fungicide can include metabolites, in which Trichoderma can release metabolites that create a fungicidal effect. Such an effect is observed even when proteases are inactivated, so it is not necessarily the proteases that provide the fungicide effect but the secondary metabolites.Trichoderma species
[0166] The feedstocks herein can be treated with protease(s) from any Trichoderma species, as well as combinations of Trichoderma species. For instance, by such treatment, the protease(s) from the Trichoderma species can enzymatically hydrolyze the plant protein or feedstock.

[0190] The biostimulant compositions and formulations herein can be any derived from a feedstock including plant proteins, after treatment with protease(s) from a Trichoderma species. In certain embodiments, a biostimulant composition includes two or more amino acids and one or more micronutrients.
[0191] The biostimulant compositions in accordance with certain disclosed embodiments can be derived from feedstock that includes a plant-based protein source. Plant-based protein sources may be selected based on their high organic matter content. These by-products can be selected by virtue of their high organic matter content, mainly proteins, and have been characterized to carry out enzymatic hydrolysis processes, obtaining said biostimulant products. Through hydrolytic processes, the functional properties of organic matter contained inagro-industrial organic by-products can be modified, which provides them with a greater capacity for agricultural application by increasing their bioavailability.
[0192] Either or both of the amino acids and oligopeptides may originate from a plant-based protein source. Some biostimulants can contain other components from a plant source, such as secondary metabolites, phytohormones, micronutrients, and / or macronutrients. Certain biostimulant compositions described herein are in liquid form or have components that are suspended in liquids. Yet other biostimulant compositions described herein are in solid form or have solid components.
[0193] The biostimulant compositions can be characterized by an amino acid profile. The amino acid profile can differ, depending on the starting raw material and hydrolysis conditions. Additionally, some raw materials can generate different peptide profiles; and some peptide profiles (oligopeptides and / or polypeptides) have greater or lesser beneficial properties, such as nutrient, antimicrobial, and antibacterial capacity. When controlled enzymatic hydrolysis of proteins is carried out, a balance can be obtained between amino acids in free form and as peptides, which gives the hydrolysate a significant nutritional role as a biostimulant that stimulates the growth and development of plants and crops and that increases the microbiological activity of the soil. The amino acids and the low molecular weight peptides that make them up can be nutritious substances that are easily absorbed and assimilated by plants, both by foliar and root routes, and can be transported to the plant's organs, such as buds, flowers, fruits.
[0194] Various types of amino acids may be present in the biostimulant composition. An amino acid profile may be characterized by relative amounts or concentrations of individual amino acids (e.g., proline, alanine, arginine) and / or by the relative amounts or concentrations of classes or types of amino acids.
[0195] In some embodiments, amino acids may be non-proteinogenic amino acids. In some embodiments, amino acids may be proteinogenic amino acids. For example, in some embodiments, any one or more of the following types of amino acids are present: aliphatic amino acids, aromatic amino acids, non-polar and neutral amino acids, polar and neutral amino acids, acidic and polar amino acids, and basic and polar amino acids. The amino acids in a biostimulant composition may be proteinogenic or non-proteinogenic (e.g., taurine and ornithine). A biostimulant composition may have at least one of the following amino acids at greater than a trace concentration: aspartic acid with asparagine, glutamic acid with glutamine, glycine, serine, threonine, histidine, tyrosine, arginine, alanine, methionine, valine, tryptophan, phenylalanine, asparagine, glutamine, isoleucine, leucine, proline, hydroxyproline, ornithine, and taurine. In some embodiments, the biostimulant composition includes at least glycine and lysine.In other embodiments, the biostimulant includes at least glutamic acid, glutamine, glycine, and lysine.
[0196] The below concentration percentages are percentages by weight of each amino acid divided by the total weight of the free amino acid component in the biostimulant composition (e.g., 33% glutamic acid and glutamine means that of the weight of amino acids in the biostimulant composition, 33% of the weight is glutamic acid and glutamine). Ranges in Table 6 are approximate concentration ranges for each amino acid produced from one example of a raw feedstock material.Table 6: Non-limiting amino acid profile
