Subject: NC_009975:1034144 Methanococcus maripaludis C6, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: This strain was isolated from intertidal sediments. Methanococcus maripaludis is a rapid growing hydrogenotrophic methanoarchaeon common in salt marshes, marine and estuarine environments in the Southeastern U.S.A. Methanococcus maripaludis is an obligately anaerobic, mesophilic, methane-producing archaeon. Growth on hydrogen and carbon dioxide results in the production of methane as a waste product. M. maripaludis stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
