Query: NC_017954:471000 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_000868:571500 Pyrococcus abyssi GE5, complete genome
Lineage: Pyrococcus abyssi; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This organism was isolated from an active chimney in the North Fiji Basin of the Pacific Ocean at a depth of 3500 meters. This organism is an obligate anaerobic, hyperthermophilic archaeon. Growth occurs at a temperature of 67-103 degrees C with optimal growth at 103 degrees C at 200 atmospheres of pressure. Increased hydrostatic pressure has been found to extend the upper growth temperature and stimulate growth.
