Query: NC_012108:2542328 Desulfobacterium autotrophicum HRM2, complete genome
Lineage: Desulfobacterium autotrophicum; Desulfobacterium; Desulfobacteraceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: It was isolated from a marine sediment in the Mediterranean sea near Venice, Italy. It is involved in the anaerobic mineralization of organic matter coming from the water column. Desulfobacterium autotrophicum is capable of growing litho-autotrophically with H2, CO2 and sulfate, but also by coupling sulfate reduction with the oxidation of fatty acids. This organism can transform tetra to dichlormethane.
Subject: NC_011883:2031222 Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774,
Lineage: Desulfovibrio desulfuricans; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774 was isolated from the rumen of a sheep. D. desulfuricans reduces sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. This organism grows anaerobically and utilizes a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. The nitrate reduction pathway is not expressed while sulfate is available. Alternatively, the sulfate reduction pathway is constitutively expressed when the cells are growing with nitrate reduction. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making this organism of interest as bioremediator. Metal corrosion, a problem that is partly the result of the collective activity of this bacterium, results in billions of dollars in losses each year to the petroleum industry. This organism is responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
