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_011958:53426 Rhodobacter sphaeroides KD131 chromosome 2, complete genome
Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to grow using photosynthesis, chemosynthesis, and usually can grow under both anaerobic and aerobic conditions. The most extensively studied bacteria with regards to its photosynthetic capabilities which includes the structure, function and regulation of its photosynthetic membranes, its mechanisms of CO2 and nitrogen fixation, cytochrome diversity and its electron transport systems. It can grow aerobically and anaerobically in the light and anaerobically in the dark. It produces an intracytoplasmic membrane system consisting of membrane invaginations where the light harvesting complexes (LH1 and LH2) and the reaction center are synthesized. Furthermore, it has the ability to detoxify metal oxides and oxyanions and hence has a role in bioremediation.
