Lineage: Methanococcus vannielii; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: A methane-producing motile coccus. This type species of Methanococcus was isolated from a San Francisco Bay, USA mud flat. Unlike other members of the genus this species grows only between 20 degrees C - 40 degrees C.
Subject: NC_009135:620312 Methanococcus maripaludis C5, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Anaerobic methane-producing archaeon. 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.
