NITRIFICATION

Definition

The aerobic bacterial conversion (oxidation) of ammonia and organic nitrogen to stable salts (nitrates): commonly by Nitrosomonas and Nitrobacter sp. bacteria. Ammonia is oxidized to nitrate in a two-step process: first ammonia is converted into nitrite by Nitrosomonas, and then nitrite is converted into nitrate by Nitrobacter. This second step is termed nitration.
