<span>During nitrification, ammonia is changed back into nitrate.</span> 
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>). 
First step- ammonia to hydroxylamine, 
Second step-hydroxylamine to nitrite, 
Third step-nitrite to nitrate. 
Nitrification together with ammonification is part of a nitrogen cycle.
