Query: NC_000961:435489 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.

General Information: Pyrococcus has similar characteristics of other thermoautotrophican archaea such as Archaeoglobus, and Methanococcus in the respect that they are all thermophilic and anaerobic. Pyrococcus differs, however, because its optimal growth temperature is nearly 100 °C and dwells at a greater sea depth than the other archaea. Studying Pyrococcus helps give insight to possible mechanisms used to endure extreme environmental conditions like high temperatures and high pressure.
