Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering microorganisms in agricultural and environmental applications face challenges such as dilution, dispersion, and inactivation in open settings, requiring high starter doses and inefficient drying methods that reduce viability.
Innovation Solution
A composition of encapsulated microorganisms with a water-permeable outer shell layer that delays release, allowing controlled propagation and release in a target environment, increasing viability and survival chances by maintaining microorganisms within the particle until they multiply and can be released effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microorganisms are applied in open settings (agriculture, environmental protection), then they can provide desired effects, but they are diluted, dispersed and inactivated/killed by the environment before providing the desired effect
Solution Approach 1:
The patent uses a hydrocolloid matrix (flexible shell) to encapsulate microorganisms, protecting them from environmental stressors such as desiccation, UV radiation, and temperature fluctuations. The matrix acts as a protective barrier that maintains microorganism viability during transport and application, directly addressing the problem of environmental inactivation.
Solution Approach 2:
The hydrocolloid matrix creates a protected microenvironment around each microorganism, isolating them from harmful external conditions. This inert protective layer prevents direct exposure to detrimental environmental factors, thereby improving survival rates in open settings.
2Reliability
If higher starter doses of microbial cells are utilized, then the desired effect can be achieved, but culturing to excess in advance of use is required
Solution Approach 1:
The microorganisms are pre-encapsulated in hydrocolloid matrices during manufacturing, which preserves their viability and protects them during storage and transport. This preliminary protective action eliminates the need for excessive culturing before application, as the encapsulated cells remain viable without requiring large-scale pre-cultivation.
Solution Approach 2:
The invention extracts microorganisms from bulk culture and encapsulates them individually in protective matrices. This separation allows for efficient storage and transport of viable cells without requiring continuous culturing, improving productivity while maintaining the ability to achieve desired effects.
3Stability of the object's composition
If microbial cells are dried to maintain stability and sterility, then stability and sterility are maintained, but most of the packaged microbial cells die
Solution Approach 1:
The hydrocolloid matrix serves as a flexible protective shell that maintains microorganism viability during drying and storage. The matrix structure preserves cellular integrity and prevents death during the drying process, while also maintaining sterility and stability throughout the product shelf life.
Solution Approach 2:
The invention uses composite hydrocolloid materials (such as alginate, carrageenan, or pectin matrices) that combine protective properties with biocompatibility. These composite materials create a stable, sterile environment that protects microorganisms during drying while maintaining their viability, resolving the contradiction between stability and viability.
4Ease of operation
If dried microbial cells are rehydrated at the target environment, then the desired activity is reestablished, but the process is inefficient due to prior cell death
Solution Approach 1:
Microorganisms are pre-encapsulated in protective hydrocolloid matrices that preserve viability during drying. This preliminary protection ensures that when rehydration occurs at the target environment, the cells are already viable and ready to become active, making the rehydration process efficient and effective without requiring compensation for prior cell death.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition enables a significant increase in microorganism concentration, ensuring timely and effective release in the target environment, even with low initial doses, enhancing crop productivity and soil viability while maintaining microorganism viability for extended periods.
Implementation Method 1
The outer shell layer is permeable to water but does not enable the release of microorganisms encapsulated therein for a predetermined period of time after rehydration
Implementation Method 2
the microorganisms are maintained or retained within the particles until they have multiplied and can be released successfully to the environment
Data Source
AI summary
A dehydrated composition containing a particle encapsulating one or more microorganisms is provided. The composition is useful for controlling the release of the microorganisms following rehydration and propagation within the particle.
