Phloretin Inhibits Quorum Sensing and Biofilm Formation in .

This study investigated the antivirulence capacity and mechanism of apple-skin-derived phloretin against NJ01, a vegetable spoilage bacterium. At 0.5 to 2 mg/mL doses, phloretin considerably inhibited the secretion of acyl homoserine lactones (AHLs), indicating that phloretin disrupted quorum sensing (QS) in NJ01.
