Nitrification is a critical process for preventing ammonia toxicity in engineered biofilter environments. This work describes the cultivation and complete genome sequence of novel AOA representative enriched from freshwater aquarium biofilter. In addition, despite common belief industry that AOB mediate oxidation, present study suggests an situ role “ Ca . Nitrosotenuis aquarius”-like biofilters.
