The AOBs have higher efficiency in the transformation of nitrogen in relation to heterotrophic bacteria, but they take longer to oxidize the ammonia in nitrite and belong to the genera Nitrosomonas, Nitrosococcus, Nitrospira
, Nitrosolobus and Nitrosovibrio.
The relative abundance of Gammaproteobacteria, Bacilli, Acidobacteria-6 and Nitrospira
were significantly different, Thaumarchaeota and PBS-25 were extremely significantly different between the two groups.

NOB belonging to Nitrospira
was also present in the reactor, which further supports the results of batch tests.
They fix atmospheric nitrogen ([N.sub.2]) converting into ammonium (N[H.sub.4]) by ammonifiying bacteria and then nitrifying bacteria such as nitrosomonas, nitrosospira and nitrosococcus converts N[H.sub.4] into N[O.sub.2] and then other genera of nitrifying bacteria like nitrobacter, nitrospira
, nitrospina and nitrococcus, oxidize N[O.sub.2] into N[O.sub.3] structure, that is most known as best form of N for plant growth and development .

In the crop rotation soil (pepper-bean-pepper), Nitrospira
presented by more than 2.5% of the sequences.
Nitrogen cycling was associated with fixation by Nitrospira
nitrifiers and oxidation by Betaproteobaceria, while available phosphorus was low enough to limit microbial growth (Schmidt et al.
Nitrosomonas and Nitrosospira are generally known as ammonia oxidising bacteria (AOB), while Nitrobacter and Nitrospira
are nitrite oxidising bacteria (NOB) (Head et al., 1993; Teske et al., 1994; Herbert, 1999).
