under aerobic assay conditions nitrite is the major reaction product but N2O is also detected at low levels. Under anaerobic conditions no nitrite is produced but N2O is detected, though at non-stoichiometric levels. The production of nitrite by Paracoccus denitrificans hydroxylamine oxidase is an oxygen-dependent reaction |
