Inhibitors | Comment | Organism | Structure |
---|---|---|---|
Ce(NH4)2(NO3)6 | 0.1 mM, stimulates the rate of oxidation of NH2OH 2.6-fold and inhibits production of HNO2 by 40% | Nitrosomonas europaea | |
Co(NO3)2 | 0.1 mM, 70% inhibition of the rate of nitrite synthesis | Nitrosomonas europaea | |
H2O2 | inhibits one step of oxidation of NH2OH to HNO | Nitrosomonas europaea | |
Mn2+ | complete inhibition of nitrite synthesis at 0.1 mM; complete inhibition of the oxidation of HNO to NO at 0.001 mM, inhibition of HNO2 synthesis is the same at pH 6,7,8 and 9 | Nitrosomonas europaea |

Ce(NH4)2(NO3)6 | 0.1 mM, stimulates the rate of oxidation of NH2OH 2.6-fold and inhibits production of HNO2 by 40% | Nitrosomonas europaea | |
Mn2+ | 0.001 mM, stimulation of NH2OH utilization, stimulation at pH 6 and pH 9 is approximately 40% greater than at pH 7 and pH 8 | Nitrosomonas europaea | |
additional information | the presence of Mn2+ results in decreased formation of NO and increased formation of N2O | Nitrosomonas europaea |
