H<sub>2</sub>metabolism is widespread and diverse among human colonic microbes
28 Apr 2016
Abstract excerpt
Microbial molecular hydrogen (H2) cycling is central to metabolic homeostasis and microbial composition in the human gastrointestinal tract. Molecular H2 is produced as an endproduct of carbohydrate fermentation and is reoxidised primarily by sulfate-reduction, acetogenesis, and methanogenesis. However, the enzymatic basis for these processes is incompletely understood and the hydrogenases responsible have not...
