Nitrite production by ammonia‐oxidizing bacteria mediates chloramine decay and resistance in a mixed‐species community

摘要

Mixed species biofilm communities that include ammonia oxidising organisms as well as heterotrophic bacteria can mediate chloramine decay through a combination of biochemical degradation through ammonia oxidation, nitrite mediated decay as well as direct effects of the biofilm matrix. Additionally, biofilm formation by heterotrophic bacteria may support biofilm formation by AOB, while the AOB supply organic carbon for the heterotrophs.
