Microbial biofilms pose a serious threat to food industry, as they are difficult to inactivate or remove owing to their inherent resistance to traditional physical and antimicrobial treatments. Bacteriophages have been suggested as promising biocontrol agents for eliminating biofilms within the food industry. The efficacy of phages (BP 1369 and BP 1370) was evaluated against Salmonella spp. in biofilms. Biofilms were grown on food (lettuce), food contact surfaces (stainless steel and rubber), and MBEC biofilm devices. The efficacy of these phages in reducing biofilms was examined following phage (10 PFU/mL) treatment for 2 h. Bacteriophage treatment reduced biofilm cells by 3.0, 2.0, and 3.0 log CFU/cm on stainless steel, rubber, and an MBEC device, respectively. The adhered viable cells on lettuce were reduced by more than 1.0 log CFU/cm with phage treatment.
微生物生物膜对食品工业构成严重威胁,因为它们对传统物理和抗菌处理具有固有抗性,难以使其失活或去除。噬菌体已被认为是消除食品工业中生物膜的有前景的生物控制剂。评估了噬菌体(BP 1369和BP 1370)对生物膜中沙门氏菌属的功效。生物膜在食品(生菜)、食品接触表面(不锈钢和橡胶)以及MBEC生物膜装置上生长。在噬菌体(10 PFU/mL)处理2小时后,检查了这些噬菌体在减少生物膜方面的功效。噬菌体处理分别使不锈钢、橡胶和MBEC装置上的生物膜细胞减少了3.0、2.0和3.0 log CFU/cm。用噬菌体处理后,生菜上附着的活细胞减少了超过1.0 log CFU/cm。
