Journal ArticleDOI
pH and peptide supply can radically alter bacterial populations and short-chain fatty acid ratios within microbial communities from the human colon.
TL;DR: It is suggested that a lowering of pH resulting from substrate fermentation in the colon may boost butyrate production and populations ofbutyrate-producing bacteria, while at the same time curtailing the growth of Bacteroides spp.
Journal ArticleDOI
Selective Colonization of Insoluble Substrates by Human Faecal Bacteria
TL;DR: It is suggested that a specific subset of bacteria is likely to be the primary colonizers of particular insoluble colonic substrates, however, for a given substrate, the primary Colonizing species may vary between host individuals.
Journal ArticleDOI
Effects of esculin and esculetin on the survival of Escherichia coli O157 in human faecal slurries, continuous-flow simulations of the rumen and colon and in calves.

TL;DR: The addition of these compounds to human faecal slurries and in vitro continuous-flow fermenter models simulating conditions in the human colon and rumen caused marked decreases in the survival of an introduced strain of E. coli O157.
Journal ArticleDOI
Dietary effects on the microbiological safety of food.
TL;DR: The potential importance of digesta flow and bacterial detachment in shedding of food-borne pathogens is discussed and one such system which, like the natural rumen, has a different turnover rate for solid and liquid digesta, was found to maintain rumen-like variables over an 11 d period.
