文摘

Atenolol biodegradation was found to be related to ammonia oxidation rate. Four products P117, P167, P227 and P267 were produced in the presence of ammonium. Two products P267 and P227 were formed in the absence of ammonium. The chemical structures of products P117, P167 and P267 were identified. A two-step biodegradation pathway of atenolol by enriched nitrifying culture is revealed.
