Query: NC_010730:627465 Sulfurihydrogenibium sp. YO3AOP1, complete genome
Lineage: Sulfurihydrogenibium; Sulfurihydrogenibium; Hydrogenothermaceae; Aquificales; Aquificae; Bacteria
General Information: Carbon fixation. Unable to oxidize hydrogen although hydrogen oxidation was thought to be universal in this group. Isolated from near-neutral-pH terrestrial hot springs in Obsidian Pool in Yellowstone National Park, USA.
Subject: NC_000909:201000 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.
