Query: NC_012804:611444 Thermococcus gammatolerans EJ3, complete genome
Lineage: Thermococcus gammatolerans; Thermococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Hyperthermophilic radioresistant marine archaeon. Thermococcus gammatolerans was isolated from hydrothermal vent chimneys located in the mid-Atlantic Ridge and Guyamas basin. When exposed to gamma radiation, this organism has a survival curve similar to Deinococcus radiodurans.
Subject: NC_000909:858840 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.
