Query: NC_009092:179226 Shewanella loihica PV-4, complete genome
Lineage: Shewanella loihica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain is an environmental isolate from the Naha Vents, Hawaii, in the Pacific Ocean. Psychrotolerant bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. Shewanella loihica is a psychrotolerant deep sea bacterium. This organism is able to reduce iron, manganese and uranium and may be useful for bioremediation at low temperatures.
Subject: NC_011883:1478173 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.
