Research Progress on Quorum Sensing System of Bacterial Biofilm

Abstract

Abstract: The quorum sensing system of bacterial biofilm is the one that the bacteria secrete signaling molecules and sense their concentration of the surrounding environment so that to regulate the expressions of certain specific genes，and to change some physiological functions and life habits of bacteria. It is one of the main regulatory mechanisms in bacteria. Based on the research of the bacterial biofilm’s quorum sensing，we can understand its internal mechanism and features，and find the best way to inhibit harmful effects of biofilms. This review focus on bacterial biofilm’s quorum sensing，such as the types，the characteristics and the related applications.

Key words: bacteria, biofilm, quorum sensing, signal molecules
