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_000909:963984 Methanocaldococcus jannaschii DSM 2661, complete genome
Lineage: Methanocaldococcus jannaschii; Methanocaldococcus; Methanocaldococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Methane-producing thermophilic archeon. Isolated from a deep-sea hydrothermal vent in the east Pacific Rise in 1982. This organism is an obligately anaerobic methane-producing archeon and was the first representative of the archaeal domain to be completely sequenced. The cells require a pH of 5.2-7 with 1.0-5.0% NaCl, optimal conditions are pH 6.0 and 3% NaCl. Fixes carbon dioxide to methane as its primary energy-producing biochemical pathway.
