Inhibitory Effects of Enterococcus faecalis Z096 on Biofilm and Quorum Sensing of Vibrio parahaemolyticus

To study the inhibitory effects of Enterococcus faecalis Z096 on the biofilm and quorum sensing (QS) system of Vibrio parahaemolyticus, the competition, elimination and exclusion were performed to simulate the interaction between Z096 and V. parahaemolyticus in microbial communities. In addition, th...

Summary:To study the inhibitory effects of Enterococcus faecalis Z096 on the biofilm and quorum sensing (QS) system of Vibrio parahaemolyticus, the competition, elimination and exclusion were performed to simulate the interaction between Z096 and V. parahaemolyticus in microbial communities. In addition, the effects of Z096 extract (Z096-E) on V. parahaemolyticus biofilm formation, mature biofilm elimination, cell surface hydrophobicity, auto-aggregation, QS signal molecule AI-2 activity, motility ability (swarming and swimming), extracellular polysaccharide and protein synthesis were further explored. The results showed that Z096 could significantly reduce the number of V. parahaemolyticus cells in plankton and biofilm by competition, elimination and exclusion, and interfere with the adhesion of V. parahaemolyticus on the carrier surface. Moreover, Z096-E could significantly inhibit biofilm formation and effectively eliminate the mature biofilm of V. parahaemolyticus. When treated with 1.6 mg/mL of Z096-E for 12 h,
