[Oxidation of nitrous oxide during decomposition of hydrogen peroxide by catalase]

Possible involvement of the catalase mechanism in the elimination of nitrous oxide was studied in model experiments. The concentration of N2O in the gaseous phase was found to decrease due to the decomposition of hydrogen peroxide by catalase. The concentration of NO increased accompanying the removal of N2O from the gaseous phase in the pressure of H2O2 and catalase. Though the observed effect is slight, the oxidation of nitrous oxide during the decomposition of H2O2 by catalase might be one of the mechanisms for biological elimination of N2O under the oxidating conditions.
