Query: NC_017954:345430 Thermogladius cellulolyticus 1633 chromosome, complete genome
Lineage: Thermogladius cellulolyticus; Thermogladius; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Obligate anaerobe. Grows optimally at a temperature of 84 deg C and pH 7.1, isolated from the hot spring in the Uzon Caldera in Kamchatka (Russia). Capable of growing by fermentation not only on proteinaceous substrates but also on cellulose. Elemental sulfur is not obligately required but stimulates growth and is reduced to H2S.
Subject: NC_007181:1094422 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.
