Nitrospinota is a bacterial phylum. Despite only few described species, members of this phylum are major nitrite-oxidizing bacteria in surface waters in oceans. By oxidation of nitrite to nitrate they are important in the process of nitrification in marine environments.[3]

Although genus is aerobic bacterium, it was shown to oxidize nitrite also in oxygen minimum zone of the ocean. Depletion of oxygen in such zones leads to preference of anaerobic processes such as denitrification and nitrogen loss through anammox. thus outweight nitrogen loss by nitrification also in these oxygen depleted zones.[4][5]

Among the cultivated isolates within the genus Nitrospina are [6][3] and .[7] Further genomes were resolved by culture-independent metagenome binning.[5] The two Nitrospina species are, however, distantly related to environmentally abundant uncultured Nitrospinota.[8] The two other strains were cultivated in 2020 each in the binary culture with alphaproteobacterial heterotroph. They are called "" and "". "" is closely related to uncultivated environmentally abundant Nitrospinota clades 1 and 2.[8]

Taxonomy[]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [9] and National Center for Biotechnology Information (NCBI)[10]
