Postbiotic screening platform for gut health optimization

Overview

This solution offers a high-throughput screening platform for evaluating postbiotics—beneficial compounds produced during fermentation—and their effects on human gut bacteria. The technology addresses a growing market need for validated, science-backed gut health products by providing a systematic method to assess how fermentation compounds impact gut bacteria growth and viability. By identifying optimal postbiotics and their key metabolites, the platform supports product development, quality monitoring, and substantiation of functional health claims for food, supplement, and beverage manufacturers.

Technical specifications

Core capabilities:

• High-throughput compound screening against standardized libraries of human gut bacteria, ranging from 48 to 40,000 bacterial isolates or communities
• Accurate replication of anaerobic conditions and nutrient availability found in the human gastrointestinal tract
• Assessment of bacterial viability, growth rates, and growth dynamics over timescales up to 72 hours
• Automated computational analysis to identify species diagnostic of beneficial or detrimental effects
• Metabolomic profiling using LC-MS targeted to computationally determined keystone species
• Development of simple, standard colorimetric assays for metabolite detection and batch monitoring

Validation history:

• Previously applied to 1,000 bacterial species across the four main human gut phyla
• Already identified 14 dietary compounds with detrimental impacts and 17 compounds with beneficial impacts on gut microbiota members

Technology readiness level

The screening technology has been extensively validated and applied across multiple research contexts, from antibiotic susceptibility detection to nutrient and metabolite utilization studies. The proposed research is structured in two stages over 4–6 months. Stage 1 involves screening fermentation compounds against defined gut bacteria libraries and characterizing microbiome growth dynamics. Stage 2 focuses on metabolic analysis to identify keystone metabolites and develop simple colorimetric assays for production batch monitoring. The platform is ready for collaborative application to specific postbiotic candidates and fermentation product development.
