Bioaugmentation enabled simultaneous biodegradation of sulfadiazine and nitrification.
Biodegradation of the common sulfanilamide antibiotic sulfadiazine (SDZ) and its inhibition of nitrification was targeted, and metagenomic analysis supported that NNB was responsible for nitrification, while bioaugmented SDAB was responsible for SDZ biodegradation that allowed simultaneous removal of NH4+-N and SDZ.
