Lineage: Thermococcus; Thermococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Sulfur-reducing, strictly anaerobic, and hyperthermophilic archaeon. Isolated from the deep-sea hydrothermal vent Guaymas Basin site in the Gulf of California at a depth of 2,000 m.
Subject: NC_000868:500249 Pyrococcus abyssi GE5, complete genome
Lineage: Pyrococcus abyssi; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This organism was isolated from an active chimney in the North Fiji Basin of the Pacific Ocean at a depth of 3500 meters. This organism is an obligate anaerobic, hyperthermophilic archaeon. Growth occurs at a temperature of 67-103 degrees C with optimal growth at 103 degrees C at 200 atmospheres of pressure. Increased hydrostatic pressure has been found to extend the upper growth temperature and stimulate growth.
