Subject: NC_007181:1295956 Sulfolobus acidocaldarius DSM 639, complete genome
Lineage: Sulfolobus acidocaldarius; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea
General Information: Sulfolobus acidocaldarius DSM 639 was isolated from and acidic hot spring in Yellowstone National Park. Extreme thermoacidophilic sulfur-oxidizing archaeon. This organsim is an extreme thermoacidophilic, sulfur-oxidizing archaeon commonly found in hot springs growing at very high temperatures. This obligate aerobe is immotile and grows at a temperature of 55-85 degrees C with optimal growth at 70-75 degrees C. The pH for growth is 1-6 with an optimum pH 2-3.
