Lineage: Methanococcus vannielii; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: A methane-producing motile coccus. This type species of Methanococcus was isolated from a San Francisco Bay, USA mud flat. Unlike other members of the genus this species grows only between 20 degrees C - 40 degrees C.
Subject: NC_000909:404961 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.
