Nitrification, a chemoautotrophic process, is carried out by a consortium of bacteria and involves production of intermediates such as nitrite (NO2 -), and nitrous oxide (N2O) as a byproduct.

Another pathway of N2 production is the anaerobic ammonium oxidation (anammox; NH4++ NO2 - → N2 + 2H2O) which, in contrast to denitrification, is carried by chemoautotrophic bacteria.
