Selective colonization of insoluble substrates by human faecal bacteria

Abstract

Insoluble plant polysaccharides and endogenous mucin are important energy sources for human colonic microorganisms. The object of this study was to determine whether or not specific communities colonize these substrates. Using faecal samples from four individuals as inocula for an anaerobic in vitro continuous flow system, the colonization of wheat bran, high amylose starch and porcine gastric mucin was examined. Recovered substrates were extensively washed and the remaining tightly attached bacterial communities were identified using polymerase chain reaction-amplified 16S rRNA gene sequences and fluorescent in situ hybridization. The substrate had a major influence on the species of attached bacteria detected. Sequences retrieved from bran were dominated by clostridial cluster XIVa bacteria, including uncultured relatives of Clostridium hathewayi, Eubacterium rectale and Roseburia species. Bacteroides species were also detected. The most abundant sequences recovered from starch were related to the cultured species Ruminococcus bromii, Bifidobacterium adolescentis, Bifidobacterium breve and E. rectale. The most commonly recovered sequences from mucin were from Bifidobacterium bifidum and uncultured bacteria related to Ruminococcus lactaris. This study suggests that a specific subset of bacteria is likely to be the primary colonizers of particular insoluble colonic substrates. For a given substrate, however, the primary colonizing species may vary between host individuals.

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.
