Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for sustainable and effective alternatives to agrochemicals that can provide plant protection from microbial pathogens while minimizing environmental harm, as excessive use of conventional pesticides can harm soil health and the environment.
Innovation Solution
The use of bioprotectant compositions comprising a cell-free supernatant derived from microbial fermentation cultures inoculated with microorganisms such as Aspergillus spp., Bacillus spp., Rhodopseudomonas spp., Candida spp., Lactobacillus spp., and others, which are applied to plants or soil to enhance antimicrobial activity and reduce pathological damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pesticides are used to protect plants from microbial pathogens, then plant protection efficacy is improved, but environmental harm and soil health degradation worsen
Solution Approach 1:
The patent utilizes microorganisms that naturally occur in the environment and convert them into beneficial bioprotectant agents. These microorganisms produce antimicrobial compounds that protect plants while being environmentally benign, effectively converting ordinary environmental microbes into protective agents that eliminate the need for harmful chemical pesticides
Solution Approach 2:
The patent introduces bioprotectant compositions as intermediary agents between plants and pathogens. These compositions contain microorganisms that act as mediators, producing antimicrobial substances that indirectly protect plants by creating a protective biochemical barrier, rather than direct contact with harsh chemical pesticides
2Object-affected harmful factors
If bioprotectant compositions are used as alternatives to agrochemicals, then environmental safety is improved, but antimicrobial activity and protection efficacy may be reduced
Solution Approach 1:
The patent employs composite bioprotectant compositions containing multiple microorganism strains working synergistically. These composite microbial communities produce a broader spectrum of antimicrobial compounds, enhancing overall protective efficacy while maintaining environmental safety through the use of naturally occurring biological agents rather than synthetic chemicals
Solution Approach 2:
The patent optimizes parameters such as microbial strain selection, culture conditions, and composition formulation to maximize antimicrobial activity. By carefully controlling fermentation parameters and selecting specific microorganism strains with high productivity of antimicrobial compounds, the composition achieves efficacy comparable to chemical pesticides while remaining environmentally benign
3Device complexity
If single-mode bioprotectants are used, then composition simplicity is improved, but protection coverage against multiple pathogens is limited
Solution Approach 1:
The patent designs bioprotectant compositions with multi-functional microbial communities that can simultaneously protect against multiple types of pathogens including fungi, bacteria, and viruses. The composite microbial strains produce diverse antimicrobial compounds that provide broad-spectrum protection, making a single composition versatile enough to handle multiple pathogen threats without requiring separate treatments for each pathogen type

Function Achieved in This Case
These bioprotectant compositions effectively protect plants from bacterial, viral, and fungal pathogens, reducing abiotic stress and promoting healthier plant growth without the adverse effects of chemical pesticides.
Implementation Method 1
These bioprotectants may act via a single- or multi-mode of action including competition, antagonism, antibiosis, stimulation of plant systemic resistance reactions, and attack and consumption of fungal resting structures.
Implementation Method 2
comprising a cell-free supernatant derived from a microbial fermentation culture inoculated with a mixture of microorganisms
