摘要:

细菌群体感应是细菌利用胞外信号分子感知外界环境变化,并启动相关基因表达来适应环境变化的一种调控系统。群体感应系统参与调控微生物的多种生活习性以及各种生理过程,已经成为生命科学相关领域的热门研究课题之一。本文主要对群体感应及信号分子类型作了阐述,并概述了水产品贮藏过程中的优势腐败菌及其群体感应对水产品腐败的影响,旨在为水产品贮藏保鲜基础理论研究提供一定借鉴。

Abstract:

Quorum sensing (QS) is a cell density dependent expression of species in bacteria mediated by signal molecules.
A variety of habits and physiological processes of microorganisms have some relationship with QS. QS has been one of the
most important research fields in life sciences. This review elaborates the various types of QS signal molecules. In addition,
the influence of QS system on aquatic product spoilage is also discussed. The aim of this paper is to provide a theoretical
reference for the preservation and shelf life prolongation of aquatic products.

Key words: quorum sensing, aquatic products, dominant spoilage bacteria
