The Claim

Bacteroidota species demonstrate the broadest metabolic capacity and largest transcriptional response to complex carbohydrates, including upregulation of over 1,600 genes in response to raffinose, whereas Bacillota and Actinomycetota exhibit more targeted, strain-specific transcriptional responses consistent with narrower substrate utilization.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Bacteroidota bacteria activate more genes and metabolize a wider range of complex carbohydrates like raffinose than Bacillota and Actinomycetota bacteria, which respond with fewer, more specific genetic changes.

See the scientific wording

Bacteroidota species exhibit the broadest metabolic capacity and largest transcriptional response to complex carbohydrates, including upregulation of over 1,600 genes in response to raffinose, while Bacillota and Actinomycetota show more targeted, strain-specific responses consistent with narrower substrate utilization.

Why this might work

Bacteroidota bacteria detect complex sugars like raffinose and activate hundreds of genes that produce specialized enzymes and transporters to break down these sugars into simple components. These components are then used to make energy and a wide range of other molecules, including acids and vitamins. Other bacteria only turn on a few genes for specific sugars, limiting what they can digest and produce.

  1. Study: Interactions between gut commensal bacteria and polysaccharides derived from algae and legumes: identification of metabolites produced and pathways involved

    Bacteroidota bacteria turn on over 1,600 genes when eating chickpea sugars, while other gut bacteria only activate a few specific genes — showing Bacteroidota are like generalists who can handle many types of fiber, and others are specialists who only like a few.
