Query: NC_013859:9500 Azospirillum sp. B510 plasmid pAB510e, complete sequence
Lineage: Azospirillum; Azospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Azospirillum are commonly isolated from the rhizosphere and root surfaces from a wide variety of plants. Azospirillum species are considered to be plant growth promoting organisms, producing plant hormones for cell elongation (auxins), cell division and growth (cytokinins) and stem elongation (gibberellins). These compounds contribute to an enhanced uptake of nutrients and water and thus increased plant growth. Azospirillum sp. B510 was isolated from rice in Japan.
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.
