摘　　要：食品相关细菌引起的生物被膜形成和食品变质是食品工业中的重大问题。研究表明细菌群体感应(Quorum sensing,QS)与被膜形成、食品腐败变质密切相关。重点对细菌产生的各种QS信号分子及其在被膜形成的作用和被膜在食品工业中的重要性做了介绍。QS信号分子与食品变质密切相关,故对QS抑制剂作为新型食品防腐剂以延长储存期限及加强食品安全的前景进行了概述。Food spoilage caused by the bacterial biofilm is a significant problems in food industry. It is indicated that quorum sensing of the bacteria plays a major role in biofilm formation and food spoilage. This review focuses on the recent research advances about various quorum-sensing signaling molecules produced by bacteria, the role of signaling molecules in biofilm formation and the significance of biofilms in food industry. As quorum-sensing signaling molecules are closely relate to food spoilage, it was also reviewed that quorum-sensing inhibitors can be developed to be used as novel food preservatives for enhance shelf life and food safety.
