Abstract

SUMMARY: is a heterotrophic nitrifying bacterium which reduces nitrite produced from ammonia to nitrogen gas, regardless of the ambient dissolved O concentration. Under certain growth conditions, nitrous oxide may be produced. The ammonia oxygenase showed a number of similarities with that of autotrophic nitrifiers [e.g. light sensitivity, Mg requirement, NAD(P)H utilization], as did the hydroxylamine oxidoreductase (cytochrome oxidation, hydrazine inhibition). However, there were also differences (e.g. hydroxylamine inhibition of ammonia oxidation) and this apparent similarity may be superficial. Control experiments with a strain of (which does not nitrify) did not show the presence of either enzyme.
