Anammox can be a microbial process where ammonia is oxidized to nitrogen fuel, with nitrite as the electron acceptor [13]. Hosokawa et al. [13] researched the cometabolism of Patescibacteria with anammox in an anammox reactor. On The idea in their examine, Patescibacteria could possibly Perform an ecological job in giving lactate and formate to other coexisting micro organism, supporting advancement during the anammox reactor.
