Research progress on bacterial biofilms in the food industry
Biofilm is the main ecological form of bacteria in the natural environment,which is a three-dimensional structured microbial community.Importantly,biofilms empower the tolerance of encased sessile bacteria to various adverse stresses.In the food industry,foodborne pathogens can form biofilms during food processing and storage,which easily cause disinfection escape and bacterial contamination and lead to toxin accumulation and food spoilage,thus threatening the health of consumers.The prevention,inhibition,and elimination of bacterial biofilms are of great importance for ensuring microbial food safety.Therefore,it is urgent to explore efficient strategies and methods for the detection,prevention,and removal of bacterial biofilms.This review summarized the current advances in biofilm studies in the food science area,including biofilm contamination in the food industry,the mechanisms of biofilm-associated stress tolerance,and elimination strategies,which helps to better understand the food safety risks caused by biofilms and provides a theoretical basis for the development of green and efficient biofilm removal technologies.
