To be able to use nitrogen, plants convert atmospheric nitrogen to nitrates, nitrites and ammonia compounds by … The oxidation of ammonia into nitrite (also known as nitritation) is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA ). AOB can be found among the Betaproteobacteria and Gammaproteobacteria. Since discovery of AOA in 2005, two isolates have been cultivated: Nitrosopumilus maritimus and Nitrososphaera viennensis. In soils the most studied AOB belong to the genera Nitrosomonas and Nitrococcus.
