The human gastrointestinal tract hosts over 100 trillion microorganisms, with disruptions to this ecosystem linked to numerous health conditions. Clinical studies have shown that dysbiosis—an imbalance in gut microbiota—correlates with inflammatory bowel disease, metabolic disorders, and compromised immune function, with bacterial diversity typically reduced by 20-30% in affected individuals.

The fundamental challenge lies in selecting and delivering viable probiotic strains that can effectively colonize the gut while producing targeted therapeutic effects under varying physiological conditions.

This page brings together solutions from recent research—including oxygen-tolerant Akkermansia muciniphila strains, targeted Bacillus compositions for pathogen reduction, engineered bacteria that synthesize fiber, and multi-strain approaches for inflammatory conditions. These and other approaches focus on practical formulation strategies that maintain bacterial viability while achieving specific health outcomes.

1. Genetically Modified Gut Bacteria Expressing Fiber-Synthesizing Enzyme for Carbohydrate Conversion

ZBiotics Company, 2023

Engineered gut bacteria that can consume carbohydrates and synthesize fiber to improve gut health. The bacteria are modified to express a fiber-synthesizing enzyme that uses carbohydrates to produce fiber in the gut. Administering these bacteria can decrease carbohydrate levels and increase fiber levels in the gut. This aims to counteract the negative effects of excessive carbohydrate consumption and insufficient fiber intake on gut microbiome composition and health.

2. Genetically Altered Adherent-Invasive E. coli with Enhanced Immune Sensitivity and Competitive Colonization Ability

THE REGENTS OF THE UNIVERSITY OF MICHIGAN, 2023

Modified adherent-invasive E. coli (AIEC) bacteria to prevent or decrease susceptibility to intestinal inflammation, colitis and IBD. The modified AIEC bacteria have mutations that increase their sensitivity to immune system killing while retaining their competitive advantage over other gut bacteria.
