Query: NC_012883:360348 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_003552:1492500 Methanosarcina acetivorans C2A, complete genome
Lineage: Methanosarcina acetivorans; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: This wild-type strain (C2A; DSM2834) is the type strain of this species and was isolated from marine sediment. Anaerobic methane-producing archeon. This organism is a strictly anaerobic, nonmotile, methane-producing Archaea responsible for virtually all biogenic methane production, a process of critical importance as a key step in the global carbon cycle. This process results in the production of significant amounts of greenhouse gas. This organism is also important in production of alternative fuels and plays a role in both agricultural and waste treatment industry. Optimal growth occurs at pH 6.5-7.0.
