Query: NC_006138:1245944 Desulfotalea psychrophila LSv54, complete genome
Lineage: Desulfotalea psychrophila; Desulfotalea; Desulfobulbaceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: This organism was isolated from marine sediments off of the coast of Svalbard, and can grow at temperatures as low as -1.7 degrees C. Sulfate-reducing bacterium. This organism grows on more complex organic compounds such as acetate, propionate, butyrate, lactate as well as by using simpler compounds such as hydrogen. This organism is an important part of global biogeochemical cycling of carbon and other nutrients.
Subject: NC_010424:214640 Candidatus Desulforudis audaxviator MP104C, complete genome
Lineage: Desulforudis audaxviator; Desulforudis; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is a gram positive sulfate reducing bacteria identified in fracture water from a borehole at a depth of 2.8 km in a South African gold mine. Water from these boreholes is very old (low-biodiversity fracture water), suggesting that these bacteria have been isolated from the Earth's surface for as much as several million years.
