The present study investigated 14 biofilm formation related genes involved in Staphylococcus aureus food isolates and further evaluated the effect of tea polyphenols and Nisin on the growth and biofilm formation of these strains.All the 16 S.aureus strains were collected from food source. 14 adhesin genes were detected by polymerase chain reaction( PCR) using specific primer.The antibacterial activity and minimal inhibitory concentration( MIC) of tea polyphenols and Nisin were tested using the microtiter-pl...
