Query: NC_010338:4015928 Caulobacter sp. K31, complete genome
Lineage: Caulobacter; Caulobacter; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Caulobacter strain K31 was isolated in an enrichment culture for chlorophenol-tolerant bacteria in groundwater from Karkola, Finland, which percolates through nutrient-poor silt and clay, and is cold (7-8oC), oxygen-deficient, iron-rich, and mildly acidic (pH 6-6.5).
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.
