Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds. [1] Types include ammonia-oxidizing bacteria ( AOB) and nitrite-oxidizing bacteria ( NOB ).
nitrifying bacterium, any of a small group of aerobic bacteria (family Nitrobacteraceae) that use inorganic chemicals as an energy source. They are microorganisms that are important in the nitrogen cycle as converters of soil ammonia to nitrates, compounds usable by plants. The nitrification process requires the mediation of two distinct groups ...

Jun 9, 2016 · Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants. Denitrifying bacteria converts nitrates back to nitrogen gas.

- Why is it that normal Nitrogen is "N" while Nitrogen in the atmosphere is "N2"?because nitrogen atoms tend to bond with other nitrogen atoms to form nitrogen molecules, which are N2.
Nitrifying bacteria are a group of bacteria that are capable of utilizing ammonia and nitrite as energy sources that allow them to synthesize carbohydrates from carbon dioxide. They are highly significant to the global nitrogen cycle and to the existence of plants. They are autotrophs (they eat themselves) and they make ‘food ...
Dec 24, 2022 · Nitrification is the net result of two distinct processes: oxidation of ammonium to nitrite (NO 2−) by nitrosifying or ammonia-oxidizing bacteria and oxidation of nitrite (NO 2−) to nitrate (NO 3−) by the nitrite-oxidizing bacteria. Nitrification is an important step in the nitrogen cycle in soil. Nitrification is an aerobic process ...
