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_009776:617532 Ignicoccus hospitalis KIN4/I, complete genome
Lineage: Ignicoccus hospitalis; Ignicoccus; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Ignicoccus hospitalis Kin4/I was isolated from gravel obtained from the shallow marine hydrothermal system of the Kolbeinsey Ridge, north of Iceland. Hyperthermophilic archaeon. Ignicoccus hospitalis, an anaerobic, hyperthermophilic, chemoautolithotroph, uses hydrogen to reduce elemental sulfur and produce hydrogen sulfide. This organism is also moderately halophilic and acidophilic. Ignicoccus hospitalis is the host organism for Nanoarchaeum equitans.
