Query: NC_009997:3483157 Shewanella baltica OS195, complete genome
Lineage: Shewanella baltica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from the Baltic Sea. A psychrophilic 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. This species is differentiated from other Shewanella spp. based on its ability to grow at 4 degrees C but not at 37, 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_007406:632436 Nitrobacter winogradskyi Nb-255, complete genome
Lineage: Nitrobacter winogradskyi; Nitrobacter; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Nitrite-oxidizing bacterium. Members of this genus are found in marine, freshwater, and terrestrial habitats, often in association with ammonia-oxidizing bacteria. These organisms oxidize nitrate, generated by the oxidation of ammonia, to nitrate and play an important role in the global nitrogen cycle. The enzyme involved in nitrite oxidation, nitrite oxidoreductase, can also reduce nitrate to nitrite in the absence of oxygen, allowing Nitrobacter sp. to grow anaerobically. Nitrobacter winogradskyi is commonly isolated from soil, fresh and sea water, sewage, and compost. This organism can grow anaerobically using nitrate as the electron acceptor, forming nitrite, nitric oxide, and nitrous oxide.
