Query: NC_000961:372000 Pyrococcus horikoshii OT3, complete genome
Lineage: Pyrococcus horikoshii; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This organism was isolated from a hydrothermal vent at Okinawa Trough in the Pacific Ocean at a depth of 1395 m. This organism is an obligate anaerobic, hyperthermophilic archaeon. Growth occurs at 80-102 degrees C with optimal growth at 98 degrees C and a pH of 7.0. Presence of elemental sulfur has been found to greatly stimulate growth.
Subject: NC_014614:1090000 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.
