Résumé

The quorum quenching (QQ) strategy has attracted increasing attention in membrane bioreactor (MBR) fouling control. However, the applicable QQ strain remains limited. This study investigated the antibiofouling performance of a new indigenous QQ bacterium, Delftia sp. JL5 (JL5) in MBR. JL5 produces intracellular acylase that irreversibly degrades N-acylhomoserine lactones (AHL), inhibited biofilm formation of quorum-sensing bacteria from activated sludge. During 120 days of operation, immobilized JL5 substantially delayed MBR biofouling by 2.1 and 2.9 times, at a flux rate of 30 L/(m
