This study aimed to assess the biofilm formation by Bacillus cereus on two novel surfaces namely: aluminum and cold steel in comparison study with stainless steel and polystyrene. Also, it aimed to study the inhibitory effect of a new strain Pediococcus acidilactici against biofilm formation by B. cereus grown on these surfaces. In this study, B. cereus M50 isolated from milky machine surface was selected as the highest biofilm producer. The number of M50 cells adhered to aluminum and stainless steel surfaces were more than that adhered to polystyrene and cold steel, respectively. The antimicrobial, anti-adhesive and SEM studies revealed that the P. acidilactici P12 culture and its cell free filtrate showed a significant potential inhibition of biofilm formation of M50 on all tested surfaces under different conditions. These results demonstrated that P. acidilactici strain are considered a new biotreatment for biofilm destruction of food borne pathogens, food biopreservation and food safety.

乳酸小球菌对附着在不同食品加工表面上的食源性生物膜生产者蜡样芽胞杆菌的抗菌和抗粘连功效。

这项研究旨在评估蜡状芽孢杆菌在两个新型表面上形成的生物膜：铝和冷钢与不锈钢和聚苯乙烯的对比研究。此外，它的目的是研究一种新的乳酸双球菌菌株对在这些表面上生长的蜡状芽孢杆菌形成生物膜的抑制作用。在这项研究中，从乳状机器表面分离的蜡状芽孢杆菌M50被选为最高的生物膜生产者。粘附在铝和不锈钢表面上的M50电池的数量分别大于粘附在聚苯乙烯和冷钢上的M50电池的数量。抗菌，抗黏附和SEM研究表明，嗜酸乳酸杆菌P12培养物及其无细胞滤液显示出在不同条件下所有被测表面上M50生物膜形成的显着潜在抑制作用。
