WebDec 24, 2024 · Denitrification is a widely used process; many facultative anaerobes use denitrification because nitrate, like oxygen, has a high reduction potential. Denitrification is a microbially facilitated process involving the stepwise reduction of nitrate to nitrite (NO 2–) nitric oxide (NO), nitrous oxide (N 2 O), and, eventually, to dinitrogen (N 2 ...

Compounds such as nitrate, nitrite, ammonia and ammonium can be taken up from soils by plants and then used in the formation of plant and animal proteins. Denitrification Denitrification completes the nitrogen cycle by converting nitrate (NO 3-) back to gaseous nitrogen (N 2 ).

WebAmmonification refers to chemical reactions in which amino groups (NH 2) associated with organic forms of nitrogen are converted into ammonia (NH 3) or ammonium (NH 4+ ).
