细菌不是孤立生活的生物,其与环境和其他生物之间以及彼此之间,通过释放信号分子感知群体数量来实现对话与交流的.该现象称为"群体感应现象(quorum sensing,QS)".已有大量研究表明,细菌性食品腐败是一种细菌群体感应现象的结果.革兰氏阴性菌是导致肉及肉制品腐败的主要微生物.因此,本文就革兰氏阴性菌的群体感应机制、群体感应信号分子及其特性进行概述,重点阐述细菌群体感应现象与肉及肉制品腐败关系的研究进展,为基于QS调控的肉及肉制品靶向防腐策略提供理论参考.

The bacteria are not isolated from each other,they were capable of perceiving the population quantity by certain signal molecular released,so that they could talk to and communicate with other organisms and their living environment,this phenomena termed quorum sensing (QS).A great deal of investigations proclaimed that bacterial food spoilage was caused by bacterial quorum sensing.The gram negative bacteria were the dominant microorganisms which were responsible for the spoilage of meat and meat produces.The quorum sensing mechanism of the gram negative bacteria and the characteristics of the signal molecular were reviewed herein.The emphasis was focused on the research progress of the relationship between the bacterial quorum sensing and the spoilage of meat and meat produces.The purpose provided theoretical references for meat and meat produces preservation strategy target to manipulate quorum sensing.
