Abstract: Pseudomonas is a genus of bacteria commonly found in contaminated raw milk. This bacterial genus can form a biofilm on equipment surfaces during the production of dairy products which causes equipment corrosion and is difficult to remove. The biofilm formed by Pseudomonas not only promotes the secretion of heat-resistant peptidases but also provides a substrate for the growth of pathogenic bacteria, posing a great risk to the safety of dairy products. This article outlines recent progress in understanding the mechanisms for the regulation of Pseudomonas biofilm formation and the environmental factors affecting Pseudomonas biofilm formation, which is helpful for the prevention and control of Pseudomonas bioflim.

Key words: Pseudomonas; bioflim; raw milk; regulation mechanism
