Ammonia-oxidizing archaea and complete ammonia-oxidizing Nitrospira in water treatment systems [PDF]
Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered water treatment systems. The sequential steps of this respiratory process are carried out by distinct microbial guilds, including ammonia-oxidizing bacteria (
