摘要: The objective of this study was to control the survival or biofilm formation Cronobacter spp. on stainless steel surfaces using Paenibacillus polymyxa. antibacterial activity a cell-free culture supernatant (CFCS) P. polymyxa against found vary with incubation time. Maximum occurred when incubated at 25 30 °C for 96 h. When CFCS introduced adhered strips up 72 h, successfully inhibited formation. Additionally, preformed were exposed suspensions in PBS 0.1% peptone water 3, 5, 7 log CFU/mL facilitate its attachment. population significantly decreased surface, regardless inoculum level carrier, present. However, microbial within 6 h and remained unchanged thereafter surface immersed an suspended 5 CFU/mL. These results indicate that is able use promising candidate competitive-exclusion microorganism
