Subject: NC_007955:1254051 Methanococcoides burtonii DSM 6242, complete genome
Lineage: Methanococcoides burtonii; Methanococcoides; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: Psychrotolerant methanogenic archeon. This organism is a strictly anaerobic, slightly halophilic archeon that was isolated from the anoxic hypolimnion (layer of cold noncirculating water below the thermocline) of Ace Lake, Antarctica. Growth occurs at a temperature between 1.7-29.5 degrees C with optimal growth at 23.4 degrees C. In addition this organism requires 0.1-0.5 M NaCl and either magnesium sulfate or magnesium chloride at a concentration greater than 0.01 M for growth.
