Lineage: Hyperthermus butylicus; Hyperthermus; Pyrodictiaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: This organism was isolated from the sea floor of a solfataric (volcanic area that gives off gas) environment with temperatures up to 112 degrees C at a depth of 9 m, off the shore of Sao Miguel Island, Azores. Hyperthermophilic sulfur-reducing archaeon. This bacterium is an extreme hyperthermophilic, anaerobic, sulfur-reducing archaeon. Grows optimally at 95-106 degress C, with a NaCl concentration of 17 g/l and a pH of 7.0.
Subject: NC_012589:1434707 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.
