Fig. 5From: The gastrointestinal microbiome in dairy cattle is constrained by the deterministic driver of the region and the modified effect of dietPhylogenetic tree of 358 high-quality strain-level genome bins (SGBs) encoding the capacity to metabolize H2 via [FeFe]-hydrogenases and [NiFe]-hydrogenases sampled from the gastrointestinal tract (GIT) regions of dairy cattle. Fermen, fermentative hydrogenases (group A1, A2, and B [FeFe]-hydrogenases); Bifurcat, electron-bifurcating hydrogenases (group A3 [FeFe]-hydrogenases). F, forage-based diet; G, grain-based dietBack to article page
