Query: NC_005791:1504500 Methanococcus maripaludis S2, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: This strain was first isolated from salt marsh sediment near Pawley's Island, South Carolina, USA. A methane-producing archaeaon. 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. Stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
Subject: NC_003901:2533000 Methanosarcina mazei Go1, complete genome
Lineage: Methanosarcina mazei; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: Methanosarcina mazei Go1 (DSM 3647) was isolated from an anaerobic sewage digester in Germany. Anaerobic methane-producing archeon. This organism is a strictly anaerobic, non-motile, methane-producing archaeon. This organism can also aggregate forming large irregular shaped clumps of cells. Occasionally these aggregates can grow to 1000 microns or more in diameter. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Can be found in decaying leaf litter, garden soil, sewage treatment sludge digestors, black mud, feces of herbivores and other urban waste and sewage products.
