Gut microbial community composition in fermentation assays
Study-scoped entity; inspect species, exposure, model and limitations on each claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
EGCG-exposed fermentations showed increases in Bacteroides, Christensenellaceae and Bifidobacterium and decreases in selected other taxa.
Experimental context and source evidence
- experimental_model
- In-vitro fermentation with microbiome profiling.
- limitations
- Taxon shifts and metabolite correlations do not establish a universally beneficial microbiome in humans.
- nutrient_topic
- EGCG collection; comparator and shared-pathway records retain their actual intervention. · Epigallocatechin-3-gallate (EGCG)
- plain_language
- EGCG also changed the experimental microbial community.
