A widespread hydrogenase supports fermentative growth of gut bacteria in healthy people Open
Disruption of hydrogen (H 2 ) cycling in the gut is linked to gastrointestinal disorders, infections and cancers. However, the mechanisms and microorganisms controlling H 2 production in the gut remain unresolved. Here we show that gut H 2…
