In vitro gut model platform for assessing postbiotic potential of plant-based fermentations

Overview

This solution offers a scientifically validated in vitro laboratory gut model platform for assessing the postbiotic potential of plant-based fermentation products. Postbiotics are bioactive compounds produced by microorganisms that confer health benefits on the host, even after the microbes themselves are no longer present. By simulating the conditions of the human gut, this platform enables partners in the food, beverage, and nutrition industries to evaluate whether their fermentation-derived products can positively influence gut microbial composition and activity, supporting product development and health claim substantiation.

Technical specifications

Validated gut model platform:

• Uses batch culture fermenters for initial screening of candidate products
• Employs a continuous flow model that replicates different regions of the colon for detailed assessment
• The only in vitro model validated against gut contents from sudden death victims, providing a close analogy to bacterial activities and composition in different areas of the gut

Analytical capabilities:

• Microbiomics to assess shifts in microbial populations, with particular focus on beneficial bacteria such as bifidobacteria
• Metabolomics to evaluate metabolic activity and identify key metabolites such as short chain fatty acids
• Dynamic monitoring to capture temporal changes in microbial composition and function

Research expertise:

• Established track record studying the impact of dietary 'biotics on the human gut
• Proven experience in cross-feeding analysis and gut microbial metabolism
• Team with strong technical capabilities in gut health research

Technology readiness level

The underlying gut model platform and 'omics methodologies are well established and have been validated through prior research. The proposed project follows a defined workflow: initial batch culture screening, followed by continuous flow model assessment of the most promising candidate, and comprehensive functionality testing using microbiomics and metabolomics. The project is estimated to take approximately seven months to complete. The approach is ready to be applied to specific plant-based fermentation products supplied by industry partners.
