Some TrOC well removed by bacteria were poorly removed by fungal enzyme. Bacterial complemented well the degradation of TrOC by fungal MBR. Biodegradation was a major TrOC removal mechanism by fungi-bacteria (F-B) MBR. Redox-mediator dosing improved removal of resistant TrOC diclofenac by F-B MBR. a r t i c l e i n f o a b s t r a c t Article history: The degradation of 30 trace organic contaminants (TrOC) by a white-rot fungus-augmented membrane Received 29 June 2013 bioreactor (MBR) was investigated.
