In ,acidic, conditions, the amount of available NH 3 is extremely low. A 1974 study by Suzuki and colleagues demonstrated that the AOB N. europaea is only able to use ammonia, rather than ammonium, which has long been considered the key reason why AOB are unable to grow in ,acidic, environments (Suzuki, Dular and Kwok 1974).

Because Nitrosomonas europaea contains ammonia-oxidizing enzyme, nitrite reductase, and nitrous oxide reductase, the conversion of ammonia to dinitrogen was tried with different reaction conditions. In aerobic reaction conditions, ammonium was converted to nitrite (NO 2 − ), while under oxygen-limiting or oxygen-free conditions, NO 2 − -N formed from ammonia oxidation by N. europaea was ...
