Bacterial Strains Enhancing Plant Biomass and Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved agricultural practices that enhance plant growth characteristics, such as biomass, yield, and stress tolerance, while being environmentally sustainable and publicly acceptable, as existing methods relying on genetically modified crops and chemical fertilizers face challenges in acceptance and sustainability.
Innovation Solution
The use of specific bacterial strains, such as the TDC-B-A100D6 strain, which act as biostimulants to enhance plant growth traits by increasing biomass, number of tillers per plant, and yield, and improving stress tolerance, without the need for genetic modification or chemical inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If genetically modified crops and chemical fertilizers are used to optimize crop performance, then plant growth and yield are improved, but environmental sustainability and public acceptance deteriorate
Solution Approach 1:
The patent uses beneficial microorganisms (bacteria and fungi) as intermediary agents to mediate between the plant and the environment. These microorganisms naturally enhance nutrient uptake, promote root growth, and increase stress tolerance without requiring genetic modification or chemical inputs, thus resolving the contradiction between productivity and environmental sustainability
Solution Approach 2:
The patent employs self-service mechanisms where plants associate with beneficial microorganisms that naturally provide growth-promoting services. The microorganisms produce plant growth hormones, solubilize nutrients, and protect against pathogens through their natural metabolic activities, eliminating the need for external chemical fertilizers and pesticides
2Productivity
If genetically modified crops are used to improve plant traits, then crop performance is enhanced, but public acceptance and market availability deteriorate
Solution Approach 1:
The patent uses beneficial microorganisms as intermediary agents that naturally enhance plant traits without genetic modification. These microorganisms serve as mediators between the plant and the environment, providing growth enhancement and stress tolerance through natural biological processes that are publicly acceptable and market-friendly
3Productivity
If chemical fertilizers are used to increase biomass and yield, then plant growth is improved, but environmental sustainability and resource efficiency deteriorate
Solution Approach 1:
The patent employs beneficial microorganisms that naturally produce plant growth hormones (auxins, gibberellins, cytokinins) and solubilize nutrients through their metabolic activities. This self-service mechanism enhances biomass and yield without requiring external chemical fertilizers, thereby improving resource efficiency and reducing substance loss
Solution Approach 2:
The patent changes the biological parameters of the plant-microbe system by introducing beneficial microorganisms that alter nutrient availability and plant physiological processes. This biological parameter change replaces chemical fertilizer input with microbial metabolic activity, improving resource efficiency while maintaining productivity
