Query: NC_011663:2123388 Shewanella baltica OS223 chromosome, complete genome
Lineage: Shewanella baltica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: 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. This species is differentiated from other Shewanella spp based on its ability to grow at 4 degrees C but not at 37 degrees C, production of N-acetyl-beta-glucosaminidase, lack of chymotrypsin, and ability to use a variety of complex carbon compounds as carbon and energy sources.
Subject: NC_012881:2310141 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.
