Solution Overview

Problem

The rehydration of stabilized microbial cultures, particularly for agricultural applications, often results in poor cell viability and low survival rates due to inadequate rehydration processes, which are critical for maintaining microbial functionality and agricultural benefits.

Innovation Solution

A system comprising a first container with a stabilized microbial culture and a second container with an aqueous rehydration solution, separated by a disruptable dividing member, allows for controlled contact to reinitiate cellular activity, using a multi-stage rehydration process to enhance microbial viability and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If stabilized microbial cultures are dehydrated for long-term storage, then shelf stability and transportability are improved, but cell viability and functionality deteriorate during rehydration

Engineering Contradiction:

Improveshelf stabilityVSAvoidcell viability

Core Design Contradiction:

Duration of action of stationary objectVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-formulating protective agents (such as sugars, proteins, or other stabilizing compounds) into the microbial culture before dehydration. These agents are incorporated during the stabilization phase to protect cellular structures during subsequent rehydration, thereby maintaining viability while achieving shelf stability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses intermediary substances (protective agents like trehalose, sucrose, or proteins) that mediate between the dehydrated state and the rehydrated state. These intermediaries form protective matrices around microbial cells during dehydration and facilitate gentle rehydration, reducing cellular shock and maintaining viability throughout the storage and reactivation process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If complex rehydration procedures are used to maintain microbial viability, then cell survival rate is improved, but ease of operation deteriorates for unskilled workers

Engineering Contradiction:

Improvecell survival rateVSAvoidease of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies self-service by designing a system where the protective agents pre-formulated in the microbial culture automatically perform the protective function during rehydration. The user simply adds water or activates the product according to simple instructions, and the protective matrix self-regulates the rehydration process, eliminating the need for complex procedural knowledge while maintaining high cell survival rates.

Inventive Principle:

Principle #25Self-service

3Productivity

If rapid rehydration is implemented for quick agricultural application, then productivity is improved, but cellular integrity and viability worsen

Engineering Contradiction:

Improveapplication speedVSAvoidcellular integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-formulating osmoprotectants and cell wall stabilizers in the microbial culture before dehydration. These agents are already in place to control the rate and manner of water uptake during rehydration, enabling rapid reconstitution without causing osmotic shock or cellular damage, thus achieving both speed and integrity.

Inventive Principle:

Principle #10Preliminary action

AI summary

A microorganism activation system for activating microorganisms prior to application of microorganisms to agricultural products includes a first container, a second container, and a disruptable dividing member. The first container includes a stabilized microbial culture therein. The second container includes an aqueous rehydration solution therein. The disruptable dividing member separates the stabilized microbial culture in the first container from the aqueous rehydration solution in the second container. Disrupting the dividing member releases the stabilized microbial culture into the second chamber to contact the aqueous rehydration solution. Contact between the stabilized microbial culture and the aqueous rehydration solution re-initiates cellular activity of the microorganisms.
