Probiotic Bacterial Composition for Adult Neurogenesis and Memory Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mechanisms by which intestinal bacteria contribute to adult neurogenesis and brain function are not well understood, and existing compositions do not effectively promote the proliferation, differentiation, and maturation of neural stem cells, nor do they maintain and enhance memory and learning ability.
Innovation Solution
A composition containing lactic acid bacteria (Enterococcus faecium), butyrate-producing bacteria (Clostridium butyricum), and amylolytic bacteria (Bacillus subtilis) is used to increase quiescent neural stem cells, promote their differentiation and maturation into neurons, activate microglia and astrocytes, and enhance memory and learning ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing compositions are used, then memory and learning ability are maintained to some extent, but they do not effectively promote the proliferation, differentiation, and maturation of neural stem cells
Solution Approach 1:
The patent uses a composite composition containing three types of bacteria (lactic acid bacteria, butyrate-producing bacteria, and amylolytic bacteria) working together to achieve both memory/learning maintenance and enhanced neural stem cell proliferation. Each bacterial type contributes specific metabolic products that collectively promote neurogenesis while maintaining cognitive function.
Solution Approach 2:
The patent changes the compositional parameters by introducing specific bacterial strains with distinct metabolic capabilities. The composition includes bacteria that produce lactic acid, butyrate, and amylolytic enzymes, creating a multi-parameter biochemical environment that simultaneously supports neural stem cell proliferation and cognitive function maintenance.
2Productivity
If intestinal bacteria are introduced to promote adult neurogenesis, then neural stem cell differentiation is enhanced, but the mechanisms and extent of contribution remain unclear
Solution Approach 1:
The patent segments the intestinal microbiota into three distinct functional bacterial groups (lactic acid bacteria, butyrate-producing bacteria, and amylolytic bacteria), allowing independent study of each group's contribution to neurogenesis. This segmentation enables researchers to measure and understand the specific mechanisms of each bacterial type while maintaining the synergistic effects of the complete composition.
3Adaptability or versatility
If a composition with multiple bacterial types is used, then comprehensive brain function benefits are achieved, but the composition complexity increases
Solution Approach 1:
The patent creates a universal composition where three different bacterial types perform multiple functions simultaneously. The bacteria collectively promote neural stem cell proliferation, differentiation, and maturation while also maintaining the blood-brain barrier and supporting overall brain homeostasis, reducing the need for separate compositions for different brain health goals.

AI summary
A composition comprising one or more bacteria selected from lactic acid bacteria (e.g., Enterococcus faecium), butyrate-producing bacteria (e.g., Clostridium butyricum), and amylolytic bacteria (e.g., Bacillus subtilis) is disclosed. The composition is useful for various applications related to brain function, including: increasing the number of quiescent neural stem cells; promoting the proliferation, differentiation, and maturation of neural stem cells into neurons; promoting the maturation of immature neurons; promoting adult neurogenesis; modulating the activation state of microglia and astrocytes; maintaining homeostasis of brain function; and maintaining and/or improving memory and/or learning.
