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_013665:1392111 Methanocella paludicola SANAE, complete genome
Lineage: Methanocella paludicola; Methanocella; Methanocellaceae; Methanocellales; Euryarchaeota; Archaea
General Information: This strain was isolated in Japan from rice paddy samples. Strain SANAE belongs to the Rice Cluster I (RC-I), a 16S rRNA and mcrA gene sequences-defined euryarchaeal lineage within Methanosarcinales and Methanomicrobiales. The RC-I group plays a key role in releasing methane from rice fields, which accounts for 10 to 25% of the global methane emissions.
