NC_001732:10678 Methanocaldococcus jannaschii DSM 2661 extrachromosomal, complete
Host Lineage: Methanocaldococcus jannaschii; Methanocaldococcus; Methanocaldococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Methane-producing thermophilic archeon. This organism is an obligately anaerobic methane-producing archeon and was the first representative of the archaeal domain to be completely sequenced. It was isolated in 1982 from a deep-sea hydrothermal vent. The cells require a pH of 5.2-7 with 1.0-5.0% NaCl, optimal conditions are pH 6.0 and 3% NaCl. M. jannaschii fixes carbon dioxide to methane as its primary energy-producing biochemical pathway.
