Anammox is often a microbial treatment through which ammonia is oxidized to nitrogen gasoline, with nitrite as the electron acceptor [thirteen]. Hosokawa et al. [13] examined the cometabolism of Patescibacteria with anammox in an anammox reactor. On the basis in their examine, Patescibacteria might Perform an ecological function in giving lactate and formate to other coexisting micro organism, supporting progress within the anammox reactor.
