Draft Genome Sequence of Methanobacterium formicicum DSM 3637, an Archaebacterium Isolated from the Methane Producer Amoeba Pelomyxa palustris

Here is reported the draft genome sequence of Methanobacterium formicicum DSM 3637, which was isolated from the methane-producing amoeba Pelomyxa palustris. This bacterium was determined to be an endosymbiont living in the cytoplasm of P. palustris and the source of methane; however, the global characteristics of its genome suggest a free-living lifestyle rather than an endosymbiotic one.
