Denitrification is defined as the “microbial reduction of nitrate or nitrite coupled to electron transport phosphorylation resulting in gaseous N either as molecular N2 or as an oxide of N.” The key to denitrification as defined is the availability of the N oxides, nitrite (NO2−) or nitrate (NO3−), which are formed ...
