Influence of short-term changes in dietary sulfur on the relative abundances of intestinal sulfate-reducing bacteria

Gut Microbes, 2019
High-protein diets may be linked to gut inflammation due to increased production of hydrogen sulfide (H2S), a potential toxin, as an end product of microbial fermentation in the colon by sulfidogenic sulfate-reducing bacteria (SRB).
