摘　　要：假单胞菌是原料乳中常见的污染微生物,其会在乳品生产设备表面形成生物膜,导致设备腐蚀,且假单胞菌难以清除。同时假单胞菌形成的生物膜能促进假单胞菌耐热酶的分泌,还可以作为致病菌的生长基质,从而给乳品安全带来风险。本文总结了假单胞菌生物膜调控机制的研究进展和影响生物膜形成的环境因素,为假单胞菌生物膜的防控提供依据。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.
