Abstract
Scanning electron microscopy, ultrasonic vibration isolation, culture surface plate count were employed in the investigation of the impact of PPR, PVC, glass, stainless steel on the formation and growth of common foodborne pathogen Listeria monocytogenes bacteria biofilms.The results showed that Listeria monocytogenes could form stable biofilms on the surface of PPR, PVC, glass, and stainless steel with TSB culturing 24 h at 35℃.The bacteria number adhering to the surface was from more to less in the order:stainless steal>PPR>PVC>glass.This illustrated that roughness of the material played a great role in the formation of biofilm.The rougher the surface, the easier the formation of the biofilm.Improving the surface properties of materials to reduce the adhesion of bacteria could be used as a kind of new way of indirect control skin membrane.
