Nitrous oxide (N2O) is a firmly established inorganic metabolite of denitrification. It is either the end product of the process or the obligatory intermediate antecedent to N2. Ample evidence for its role comes from physiological, biochemical, and genetic work as well as from isotope studies. Involvement of N2O in denitrification is now documented to such an extent, that the existence of a copper and/or iron-containing metalloflavoprotein (EC, described to form N2 from NO (Chung and Najjar, 1956; Fewson and Nicholas, 1961), must be questioned. N2O is also a product of denitrification by nitrifiers and of NO 3 and NO 2 metabolism of non-denitrifying microorganisms.
