aerobic respiration, using nitrite as electron donor
aerobic respiration, using nitrite as electron donor
The oxidation of nitrite (NO2) to nitrate (NO3), using oxygen (O2) as the electron acceptor. Nitrite oxidation is the final step in nitrification, the oxidation of ammonia to nitrate, and nitrite oxidoreductase (NOR) is the key enzyme complex that catalyzes the conversion of nitrite to nitrate in nitrite oxidizing species.
