General Information: Acidophilic archaeon. This organism is an obligate aerobic, hyperthermophilic, acidophilic, sulfur-metabolizing archaeon. This organism was isolated from Beppu Hot Springs in the geothermal area of Kyushu Island, Japan. Growth occurs optimally at 80°C and pH 2.5-3.
Subject: NC_009073:1708544 Pyrobaculum calidifontis JCM 11548, complete genome
Lineage: Pyrobaculum calidifontis; Pyrobaculum; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: This organism is a facultatively anaerobic, hyperthermophilic archaeon, first isolated from a hot spring in the Philippines. Pyrobaculum calidifontis cannot use sulfur compounds for anaerobic growth and is only able to grow anaerobically using nitrate as an electron acceptor.
