Role of dietary sulphate in the regulation of methanogenesis in the human large intestine.
Hydrogen produced during colonic fermentation may be excreted, or removed by H2 consuming bacteria such as methanogenic and sulphate reducing bacteria. In vitro, sulphate reducing bacteria compete with methanogenic bacteria for hydrogen when sulphate is present. In this study the hypothesis that sulphate in the diet could alter CH4 production in vivo has been tested. Six methane excreting volun...
متن کاملMicrobial production of volatile sulphur compounds in the large intestine of pigs fed two different diets.
AIMS To investigate the production of volatile sulphur compounds (VSC) in the segments of the large intestine of pigs and to assess the impact of diet on this production. METHODS AND RESULTS Pigs were fed two diets based on either wheat and barley (STD) or wheat and dried distillers grains with solubles (DDGS). Net production of VSC and potential sulphate reduction rate (SRR) (sulphate sa...
متن کاملAlternative pathways for hydrogen disposal during fermentation in the human colon.
Hydrogen gas, which is produced during fermentation in the human colon, is either excreted in breath or metabolised by gut bacteria through a variety of pathways. These may include methanogenesis, dissimilatory sulphate reduction, and acetogenesis. To determine which of these routes predominates in the large intestine, stools were taken from 30 healthy subjects and incubated as 5% (w/v) slurrie...
متن کاملThe contribution of sulphate reducing bacteria and 5-aminosalicylic acid to faecal sulphide in patients with ulcerative colitis.
BACKGROUND Butyrate oxidation within the colonocyte is selectively inhibited by hydrogen sulphide, reproducing the metabolic lesion observed in active ulcerative colitis. AIMS To study generation of hydrogen sulphide by sulphate reducing bacteria (SRB) and the effects of 5-aminosalicylic acid (5-ASA) in patients with ulcerative colitis in order to identify a role of this noxious agent in path...
متن کاملIntroduction of Microbial as a Major Factor in the Human Body
The aim of this study is introduction on microbials as an effective agent in the human body. Microbial (symbiotic microorganisms) means the general and universal ecosystem of riches, all genes and masses of micronutrients, regardless of their genera and species, are referred to in a particular section. The symbiotic microbials have a symbiotic relationship with host creatures. This means that t...
