Production of Nitrous Oxide as a Product of Nitrite Metabolism by Enteric Bacteria
Biological denitrification is part of the global nitrogen cycle in which NO3 − and NO2 − are converted to gaseous products such as nitrous oxide (N2O) and N2 (Payne 1973, and this volume; Delwiche and Bryan, 1976; Knowles, 1978). Several microorganisms are known to denitrify NO2 − only to. nitrous oxide (an environmental pollutant), while in other organisms N2 is the final product of denitrification. Although there is a large body of literature in the area of biological denitrification, very little is known about the organization and the mechanism of regulation of the genes involved in this process (see also Carlson and Ingraham, this volume; Thayer and Huffaker, this volume).
