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_014836:1180454 Desulfurispirillum indicum S5 chromosome, complete genome
Lineage: Desulfurispirillum indicum; Desulfurispirillum; Chrysiogenaceae; Chrysiogenales; Chrysiogenetes; Bacteria
General Information: Environment: Fresh water; Temp: Mesophile. This is the first cultured species of the proposed new genus "Desulfurispirillum", and the sequencing of its genome will expand the range of experimental approaches that researchers can use to characterize its metabolic pathways for energy production and understand how these pathways are regulated. This organism is notable for its ability to reduce selenate to selenite and further to insoluble elemental selenium, in a process called dissimilatory selenate reduction.
