Hint: Nitrifying bacteria convert ammonia, the most reduced form of nitrogen in the soil, to nitrate, the most oxidized form. This is essential in and of itself for soil ecosystem function, as it helps to control soil nitrogen losses through leaching and nitrification of nitrate.

Complete answer:
Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira, and Nitrococcus are genus of chemo lithotrophic bacteria that include various species.
The oxidation of inorganic nitrogen compounds provides energy to these bacteria. Ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) are two types (NOB).
Many bacteria that are a nitrification system are complicated within the internal membrane and are composed of the most important nitrified enzymes such as monooxygenase ammonia (which converts ammonia into hydroxylamine), oxide-reductase hydroxylamine (which converts hydroxylamine into nitrogen oxide, which is then oxidised to nitrite through an unspecific enzyme), nitrogen oxidation (which converts nitrate oxide).
The process of converting ammonium nitrogen to nitrate nitrogen is known as nitrification. It consists of two stages: nitrite formation and nitrate formation. Nitrosomonas bacteria convert ammonium ions to nitrites in the first step. Nitrobacter, for example, converts nitrites to nitrates in the second stage. Pseudomonas converts nitrates back to nitrogen oxide (denitrification). Another bacterial community that has little to do with nitrogen fixation is Mycobacterium. It causes a variety of diseases in humans, including tuberculosis, which is caused by Mycobacterium tuberculosis.

Nitrifying bacteria can be found in a variety of taxonomic classes, and they are most abundant where there is a lot of ammonia (areas with extensive protein decomposition, and sewage treatment plants). Because of the high ammonia content, nitrifying bacteria flourish in lakes and rivers streams with high inputs and outputs of sewage and wastewater, as well as freshwater.
