Nitrifying bacteria such as Nitrosomonas play an important role in providing nitrogen to plants and limiting carbon dioxide fixation. They are found widely distributed in soil or water, where there are large amounts of ammonia, such as lakes or streams into which treated and untreated sewage is pumped.
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate. In itself, this is important for soil ecosystem function, in controlling losses of soil nitrogen through leaching and denitrification of nitrate.
Nitrosomonas are important in the global biogeochemical nitrogen cycle, since they increase the bioavailability of nitrogen to plants and in the denitrification, which is important for the release of nitrous oxide, a powerful greenhouse gas.
In the aquarium, bacteria are mostly responsible for breakdown waste . The most frequent process is the breakdown of protein into ammonia, then nitrite into nitrate . This process of waste disposable is known as the Nitrogen Cycle, which uses Nitrosomonas and Nitrobacter.
Nitrifying bacteria are ubiquitous in soils. Some heterotrophic organisms are also capable of nitrification.
