<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.

The bacteria must be outcompeted and substituted by bacteria that have gone this genetic factor. In addition, antibiotic resistance is a natural phenomenon. Once an antibiotic is used, bacteria that can fight that antibiotic have a greater chance of existence than those that are vulnerable. The vulnerable bacteria are exterminated or inhibited by an antibiotic, subsequent to a selective weight for the existence of resilient tensions of bacteria. Around opposition happens without human deed as bacteria can yield and use antibiotics in contradiction of other microorganisms, prominent to a low-level of the natural assortment of opposition to antibiotics. Though, the presently advanced points of antibiotic resilient bacteria are credited to the abuse and abuse of antibiotics.
