Query: NC_012881:3727150 Desulfovibrio salexigens DSM 2638, complete genome Lineage: Desulfovibrio salexigens; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria General Information: Isolation: mud in British Guyana; Temp: Mesophile; Temp: 37 C; Habitat: Mud. Desulfovibrio are sulfate-reducing bacteria which reduce sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. These organisms typically grow anaerobically, although some can tolerate oxygen, and they utilize a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making these organisms of interest as bioremediators. These organisms are responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.

General Information: This is a thermophilic, facultatively mixotrophic sulfur-oxidizing bacterium. Thermus scotoductus SA-01 was isolated from fissure water in a South African gold mine. This organism is a thermophilic bacterium which was isolated from fissure water in the Witwatersrand Supergroup at a depth of 3.2 km below surface in a South African gold mine. It is a 2.9-billion-year-old formation of low permeability sandstone and shale with minor volcanic units and conglomerates. The ambient temperature of the rock is approximately 60°C. Samples were collected from a freshly mined rock surface and from a water-producing borehole that penetrated 121 m horizontally into the formation at a depth of 3,198 m. T. scotoductus SA-01 is a facultative anaerobe capable of coupling the oxidation of organic substrates to reduction of a wide range of electron acceptors, including nitrate, Fe(III), Mn(IV) or S(0) as terminal electron acceptors.
