Nitrous Oxide Production

Conditions for the production of nitrite and nitrous oxide by an obligate methanotroph, Methylosinus trichosporium (OB 3b), were studied. The rate of nitrite production [Formula: see text] was correlated with the concentration of ammonia up to 20 mM in the presence of sufficient amounts of oxygen and inversely correlated with the amounts of methane in the system. The rate of nitrous oxide (N2O) production [Formula: see text] was correlated positively with [Formula: see text] and the amount of nitrite produced and inversely with the oxygen concentration in the system. Nitrite started to disappear when either oxygen or methane or both were depleted, but only a part of the loss could be accounted for by an increase in N2O. Maximum rates of nitrite and N2O production by Ms. trichosporium were 6.9 ×5 1016 and 2.2 × 10−17 mol∙cell−1∙day−1, respectively. These values are about 0.2 and 1.6% of the values for Nitrosomonas europaea. Therefore, production of nitrite and N2O by methanotrophs in aquatic environments may not be as significant as that of Nitrosomonas.
