Bio-stimulant Production via Direct Soil Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil depletion of beneficial microorganisms due to the use of synthetic fertilizers hinders plant growth and health, as existing bio-stimulant production methods are costly, time-consuming, and require host plants for cultivation, leading to suboptimal microorganism concentrations and contamination risks.
Innovation Solution
A method involving a starting material from natural environments, such as humus or soil, is used to cultivate beneficial microorganisms directly, without host plants, using a carbohydrate-rich mixture that ferments to create a viscous, water-soluble bio-stimulant absorbed by carriers like zeolite or biochar, allowing for customizable pH and micronutrient inclusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beneficial microorganisms are cultivated on host plants and then harvested, then the microorganisms can be obtained for soil inoculation, but the production process becomes time-consuming and costly
Solution Approach 1:
The patent extracts the beneficial microorganisms directly from natural environments (soil, humus, compost) without requiring host plant cultivation. This extraction approach eliminates the time-consuming host plant growth phase while obtaining viable microorganisms that can be directly processed into bio-stimulant products.
Solution Approach 2:
The patent performs preliminary enrichment of microorganisms in controlled fermentation conditions before final product formulation. This preliminary action in optimized media allows rapid multiplication and concentration of target microorganisms without the extended host plant cultivation period, reducing overall production time while maintaining viability.
2Quantity of substance
If host plants are used to cultivate microorganisms, then sufficient microorganism concentration can be achieved, but the production cost increases
Solution Approach 1:
The patent uses inexpensive, readily available materials such as agricultural byproducts, plant residues, and simple fermentation media instead of costly host plants. These disposable substrates can be easily sourced and processed, significantly reducing production costs while still achieving sufficient microorganism concentrations through controlled fermentation.
Solution Approach 2:
The patent optimizes fermentation parameters (temperature, pH, nutrient composition, aeration) to maximize microorganism growth rates and final concentrations. By controlling these parameters in batch or continuous fermentation systems, high cell densities are achieved more efficiently and economically compared to host plant cultivation methods.
3Productivity
If microorganisms are grown in conventional media, then growth can be supported, but contamination risks increase
Solution Approach 1:
The patent implements preliminary sterilization and sanitation measures on substrates and fermentation equipment before inoculation. Selective media formulations with specific pH levels, redox potentials, and nutrient compositions are used to create conditions that favor target microorganisms while inhibiting contaminants. This preliminary anti-action prevents contamination rather than addressing it after occurrence.
Solution Approach 2:
The patent creates localized microenvironments within the fermentation system with specific pH gradients, oxygen levels, and nutrient distributions that are optimized for target microorganism growth. These localized conditions with tailored quality parameters make the environment less suitable for contaminating organisms, thereby reducing contamination risks while maintaining high productivity.
