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_012589:1917421 Sulfolobus islandicus L.S.2.15, complete genome
Lineage: Sulfolobus islandicus; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea
General Information: Sulfolobus islandicus L.S.2.15 (Lassen #1) was isolated from Lassen National Park in California, USA. Hyperthermophilic acidophilic sulfur-metabolizing archeon. Sulfolobus islandicus is a thermo-acidophilic archeae commonly identified in hot, acidic sulfur springs. This organism can grow both chemoautotrophically, using sulfur or hydrogen sulfide, and heterotrophically. S. islandicus can play host to a number of plasmids and viruses which may be useful in developing tools for genetic analysis. In addition, Sulfolobus islandicus isolates from different areas in Russia, Iceland, and the United States have been shown to be genetically distinct from each other making this organism useful for comparative analysis.
