Query: NC_009776:707785 Ignicoccus hospitalis KIN4/I, complete genome
Lineage: Ignicoccus hospitalis; Ignicoccus; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Ignicoccus hospitalis Kin4/I was isolated from gravel obtained from the shallow marine hydrothermal system of the Kolbeinsey Ridge, north of Iceland. Hyperthermophilic archaeon. Ignicoccus hospitalis, an anaerobic, hyperthermophilic, chemoautolithotroph, uses hydrogen to reduce elemental sulfur and produce hydrogen sulfide. This organism is also moderately halophilic and acidophilic. Ignicoccus hospitalis is the host organism for Nanoarchaeum equitans.
Subject: NC_009662:383381 Nitratiruptor sp. SB155-2, complete genome
Lineage: Nitratiruptor; Nitratiruptor; Nautiliaceae; Nautiliales; Proteobacteria; Bacteria
General Information: This strain was isolated from a deep-sea hydrothermal vent in the Iheya North field in the Mid-Okinawa Trough, Japan as part of a larger diversity study. This rod-shaped bacterium grows chemolithoautotrophically and can utilize a wide spectrum of electron donors and acceptors (i.e. hydrogen, sulfur compounds, nitrate and oxygen). It can occupy different ecological niches, and its metabolic versatility probably enables it to adapt to the geochemical variability in deep-sea hydrothermal environments.
