NITROSOMONAS

Definition

Nitrobactersp. bacteria (and Nitrosomas) play an important role in the aerobic bacterial conversion (oxidation) of ammonia and organic nitrogen to stable salts (nitrates). 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.
