Query: NC_000961:1481685 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_003552:4054908 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.
