Genome Sequence of Candidatus Methanomethylophilus alvus Mx1201, a Methanogenic Archaeon from the Human Gut Belonging to a Seventh Order of Methanogens

We report the draft genome sequence of Candidatus 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.
