Editing Acidobacteriota (section)

=== Nitrogen ===
There has been no clear evidence that Acidobacteriota are involved in nitrogen-cycle processes such as [[nitrification]], [[denitrification]], or [[nitrogen fixation]].<ref name=":022"/> However, ''[[Geothrix fermentans|Geothrix fermantans]]'' was shown to be able to reduce nitrate and contained the norB gene.<ref name=":022"/> The NorB gene was also identified in ''[[Koribacter versatilis|Koribacter verstailis]]'' and ''[[Solibacter usitatus]]''.<ref>{{Cite journal|last1=Coates|first1=J.
