Nitrobacter winogradskyi is a gram-negative nitrite-oxidizing bacteria from the genus of Nitrobacter.
Nitrobacter winogradskyi and other nitrite-oxidizing bacteria (NOB), carry out a key step in the nitrogen cycle by converting nitrite, the end product of ammonia oxidation, into nitrate. Nitrification, which is initiated by the ammonia-oxidizing bacteria (AOB), is thereby completed by the action of the NOB.
N. winogradskyi is metabolically versatile. It can grow as a chemolithoautotroph by deriving energy from nitrite oxidation and fixing carbon dioxide as its source of carbon. In the absence of nitrite, N. winogradskyi can grow as a chemoorganoheterotroph and utilize organic compounds as sole carbon and energy sources (Bock et al., 1986; Bock et al., 1991) . When provided with a combination of nitrite and organic compounds, N. winogradskyi can utilize both substances simultaneously in mixotrophic growth (Bock et al., 1986; Bock et al., 1991). Finally, growth of N. winogradskyi can occur in aerobic as well as anoxic environments, and in the latter case is supported by the use of nitrate as its terminal electron acceptor (Bock et al., 1988).
