Methanomassiliicoccus intestinalis” Issoire-Mx1 is a methanogenic archaeon found in the human gut and is a representative of the novel order of methanogens related to
. Its complete genome sequence is presented here.
We report the draft genome sequence of “
Methanomethylophilus alvus” Mx1201, a methanogen present in the human gut. It was enriched from human feces under anaerobic conditions with methanol as the substrate. Its circular genome, of around 1.7 Mb, contains genes needed for methylotrophic methanogenesis from methanol and tri-, di-, and monomethylamine.
