Query: NC_012883:104987 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_014614:6115 Clostridium sticklandii, complete genome
Lineage: Clostridium sticklandii; Clostridium; unclassified Peptostreptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: This Clostridium (HF strain, ATCC 12662) was initially found associated with Methanococcus vannieli in formate-enriched cultures. After its isolation in pure culture, it was shown that this organism is capable of fermenting amino acids. Biochemical studies have shown that C. sticklandii obtains energy for growth from oxidation-reduction reactions between specific amino acid pairs. Clostridium sticklandii is a Gram-positive bacterium with low (G +C) content that is capable of fermenting amino acids.
