摘要: ABSTRACT Bacteria use quorum sensing (QS) systems to communicate with each other and regulate microbial group behavior, such as the secretion of virulence factors, including biofilm formation. In order explore safe, edible agents, potential star anise (SA) an anti-QS antibiofilm agent its possible application in milk safety were investigated. Staphylococcus aureus, Salmonella Typhimurium, Pseudomonas aeruginosa, biosensor strain Chromobacterium violaceum selected test strains for QS, biofilm, exopolysaccharide assays. The percent acidities total plate counts determined evaluate quality biofilm-inoculated noninoculated milk. yield SA extraction was 25.90% ± 0.2% (w/w). At sub-MIC, extract did not show any effect on bacterial growth. production violacein inhibited by 89% extract. also formation up 87% a dose-dependent manner. Inhibition rates 70.45%, 42.82%, 35.66% were...
