Abstract

Faecalibacterium prausnitzii is one of the most abundant commensal bacteria in the healthy human large intestine, but information on genetic diversity and substrate utilization is limited. Here, we examine the phylogeny, phenotypic characteristics, and influence of gut environmental factors on growth of F. prausnitzii strains isolated from healthy subjects. Phylogenetic analysis based on the 16S rRNA sequences indicated that the cultured strains were representative of F. prausnitzii sequences detected by direct analysis of fecal DNA and separated the available isolates into two phylogroups. Most F. prausnitzii strains tested grew well under anaerobic conditions on apple pectin. Furthermore,F. prausnitzii strains competed successfully in coculture with two other abundant pectin-utilizing species,Bacteroides thetaiotaomicron and Eubacterium eligens, with apple pectin as substrate, suggesting that this species makes a contribution to pectin fermentation in the colon. Many F. prausnitzii isolates were able to utilize uronic acids for growth, an ability previously thought to be confined to Bacteroides spp. among human colonic anaerobes. Most strains grew on N-acetylglucosamine, demonstrating an ability to utilize host-derived substrates. All strains tested were bile sensitive, showing at least 80% growth inhibition in the presence of 0.5 μg/ml bile salts, while inhibition at mildly acidic pH was strain dependent. These attributes help to explain the abundance of F. prausnitzii in the colonic community but also suggest factors in the gut environment that may limit its distribution.

  • Butyrate is a key energy source for intestinal epithelial cells and contributes to barrier integrity, T-cell regulation, pathogen resistance, inflammatory response, and metabolic homeostasis.

    “Butyrate is a key energy source for intestinal epithelial cells and contributes to barrier integrity, T-cell regulation, pathogen resistance, inflammatory response, and metabolic homeostasis. 36,37”

    From Comparative Genomic Insights into Pangenome Diversity and Functional Adaptation of Akkermansia and Faecalibacterium as Gut-Associated Next-Generation Probiotics: A Systematic Review (2026) · cites this paper as [36]

    The paper’s introductory discussion (page not supplied) describes butyrate as the preferred energy source for colonocytes and says its effects on inflammation benefit intestinal health. It does not address barrier integrity, T-cell regulation, pathogen resistance, or metabolic homeostasis. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
