冷等离子体对微生物生物膜抑制作用的研究进展

日益严峻的生物膜污染给食品和医疗等行业的生产安全带来了巨大的威胁。与一般存在于食品中的浮游微生物不同，微生物形成的生物膜有其独特的结构和功能性质，因此生物膜对杀菌处理具有更强的抵抗能力，而寻找绿色环保的抗生物膜技术也成为人们日益关注的问题。作为一种新型的杀菌技术，冷等离子体杀菌操作简单、杀菌效果显著、能耗低，还可以很好地保持食品颜色、质地以及营养价值，在食品领域引起了广泛关注。本综述主要对冷等离子体破坏生物膜形成的机理、影响因素以及应用情况3 个方面进行介绍，旨在为冷等离子体抗生物膜技术在食品工业中的应用提供理论支持。

Recent Progress in Inhibition of Microbial Biofilm Formation by Cold Plasma

The increasingly serious problem of biofilm pollution has posed a great threat to the safety of foods and medical products. Different from planktons in foods, biofilms formed by microorganisms are more resistant to bactericidal treatment due to their unique structures and functional properties. Therefore, discovering a green anti-biofilm technology has become a growing concern. As a new sterilization technology, cold plasma is simple, effective and low-energy-consuming, and it can well maintain the color, texture and nutritional value of foods, so that it has attracted widespread attention in the food field. This review mainly describes the mechanism by which cold plasma destroys biofilm formation, the factors influencing the effect and the application of cold plasma with a view to providing theoretical support for the application of cold plasma as an anti-biofilm technology in the food industry.
