Plant Bioreactor Microbe Packaging for Scalable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cultivating and storing microbes are limited by contamination, high costs, and the inability to scale up difficult-to-cultivate species, particularly plant-associated microbes, which are essential for industrial applications but often fragile and compromised by environmental stresses.
Innovation Solution
A method involving the introduction of microbes into plant tissues, where they replicate and are packaged into seeds, allowing for shelf-stable storage and scalable expansion using established agricultural practices, enabling the co-cultivation of multiple microbial species within plant bioreactors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional lab or industrial cultivation methods are used, then microbial production can be achieved, but scaling up difficult-to-cultivate species is limited and contamination risks increase
Solution Approach 1:
The patent uses plant tissues as an intermediary host system to cultivate microbes. The plant bioreactor serves as a mediator between the difficult-to-cultivate microbes and the final production system, providing a controlled environment that reduces contamination risks while enabling scalable production through agricultural practices.
Solution Approach 2:
The plant-based bioreactor system utilizes the plant's own biological processes and structures to support microbial growth. The plant provides nutrients, protection, and a structured environment for microbes, reducing the need for external contamination controls and complex industrial infrastructure.
2Duration of action of stationary object
If traditional storage methods are used, then microbial storage is possible, but shelf-life during long-term storage is compromised and viability decreases
Solution Approach 1:
The patent embeds microbes within plant seed structures, nesting the microbial population inside a protective biological container. The seed coat and internal seed structures provide physical protection and a controlled microenvironment that maintains microbial viability during long-term storage at room temperature, extending shelf-life significantly.
Solution Approach 2:
The plant seed interior creates a relatively inert and protected environment for the stored microbes. The seed structure isolates the microbes from harmful external factors such as oxygen exposure, moisture fluctuations, and environmental contaminants, thereby maintaining viability during extended storage periods.
3Productivity
If conventional cultivation systems are used, then microbial growth can be achieved, but environmental stresses compromise microbial integrity and fragility increases
Solution Approach 1:
The plant bioreactor system provides pre-established protection against environmental stresses before the microbes are exposed to harsh conditions. The plant tissue acts as a cushioning layer that buffers microbes from temperature extremes, pH fluctuations, and other environmental stresses during both cultivation and storage phases.
Solution Approach 2:
The patent utilizes the plant's ability to maintain stable internal parameters (temperature, humidity, pH, nutrient availability) that are optimal for microbial growth. By changing the environment from external laboratory/industrial controls to internal plant-based control, the system creates more stable conditions that reduce microbial fragility.
4Productivity
If industrial cultivation methods are used, then large-scale production is possible, but costs increase and system complexity increases
Solution Approach 1:
The plant-based system serves multiple functions simultaneously: it acts as a growth substrate, protection barrier, storage container, and delivery mechanism for the microbes. This multi-functionality reduces the need for separate industrial infrastructure components, thereby reducing overall system complexity while maintaining scalability through agricultural expansion.
Solution Approach 2:
The patent utilizes short-lived plant growth cycles and disposable plant biomass to produce and store microbes. Rather than investing in permanent, complex industrial facilities, the system uses transient plant hosts that can be grown, harvested, and discarded in agricultural cycles, reducing capital costs and system complexity.
