Query: NC_009635:1322860 Methanococcus aeolicus Nankai-3 chromosome, complete genome
Lineage: Methanococcus aeolicus; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Anaerobic methane-producing archeon. Methanococcus aeolicus was isolated from deep marine sediment from the Nankai Trough off the coast of Japan. This organism is a methanogen, able to use hydrogen or formate to reduce CO2.
Subject: NC_000909:762859 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.
