Query: NC_012883:1603744 Thermococcus sibiricus MM 739, complete genome
Lineage: Thermococcus sibiricus; Thermococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Thermococcus sibiricus is a hyperthermophilic anaerobic archaeon isolated from a well of the never flooded oil-bearing Jurassic horizon of the high-temperature Samotlor oil reservoir (Western Siberia). The organism is indigenous to the reservoir and survived over geologic time by metabolizing buried organic matter from the original oceanic sediment.
Subject: NC_005791:1028500 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.
