Query: NC_009718:1272296 Fervidobacterium nodosum Rt17-B1, complete genome
Lineage: Fervidobacterium nodosum; Fervidobacterium; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Fervidobacterium nodosum is a thermophilic, Gram-negative, motile, non-sporulating, glycolytic, obligately anaerobic rod that exists singly, in pairs or in chains. Fervidobacterium nodosum was isolated from a hot spring in New Zealand. Its optimal growth temperature is 65 to 70 degrees Celsius. The cellular morphology of this organism, a member of the Thermotogales, is characterized by a terminal spherical extension of the cell envelope.
Subject: NC_011883:1478173 Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774,

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.
