In … WebNitrification, the oxidation of NH 4 + to NO 3 − (eqn [3]), occurs readily in oxic environments, such as well drained soils, through the activity of nitrifying prokaryotes. This process is …

WebDec 24, 2024 · Key Points. Denitrification generally proceeds through a stepwise reduction of some combination of the following intermediate forms: NO 3 − → NO 2 − → NO + N 2 O → N 2.; Generally, several species of bacteria are involved in the complete reduction of nitrate to molecular nitrogen, and more than one enzymatic pathway has been identified … WebNitrification is a microbial process carried out by Nitrosomonas. Reduced nitrogen compounds are sequentially oxidised to nitrite and nitrate in this biological process. Two groups of autotrophic nitrifying bacteria primarily accomplish the nitrification process.
