Subject: NC_009051:657000 Methanoculleus marisnigri JR1, complete genome
Lineage: Methanoculleus marisnigri; Methanoculleus; Methanomicrobiaceae; Methanomicrobiales; Euryarchaeota; Archaea
General Information: Methanogen present in marine and freshwater sediments. Methanoculleus marisnigri was first isolated from sediment from the Black Sea, but has also been identified in freshwater sediments. This organism can use hydrogen, formate, and secondary alcohols, such as propanol and butanol, for methanogenesis.
