Query: NC_003413:1448377 Pyrococcus furiosus DSM 3638, complete genome
Lineage: Pyrococcus furiosus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This strain was isolated from a shallow marine solfataric (volcanic area that gives off sulfuric gases) region at Vulcano Island, Italy. This organism is a strictly anaerobic, hyperthermophilic archaeon. Growth occurs at temperatures between 67 and 103 degrees C, with optimal growth at 100 degrees C and a pH of 7.0. This organism is highly motile due to a bundle of flagella.
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.
