Abstract:

Bacterial biofilm is the condition under which microorganisms survive by adhering to the medium surface and
forming a large number of bacterial colonies. The dense structure of bacterial biofilm enables bacteria to survive in adverse
environmental conditions. In the food industry, it is impossible to completely eliminate bacterial contamination due to
the formation of biofilm. Meanwhile, in the medical field, biofilm is one of the major reasons for repeated attacks and
difficult control of many chronic and infectious diseases because of the drug resistance. In this paper, the recent progress in
understanding of bacterial biofilm is systematically reviewed, and future development is proposed.

Key words: food-borne pathogenic bacteria, biofilm, influencing factors, food industry
