摘要：细菌生物被膜是细菌耐药性形成的重要机制之一，是许多感染性疾病难以控制的主要原因，也是食品加工中存在的重大污染源。在生物被膜形成过程中，细菌的群体感应系统起重要作用。文章在现有的理论和研究基础上，就细菌生物被膜的特性以及群体感应系统在细菌生物被膜形成过程中的作用进行综述，旨在为通过群体感应抑制剂抑制生物被膜的形成提供全新的研究思路。

英文摘要：

Bacterial biofilm is one of the important mechanisms of the formation of bacterial resistance. Biofilm is the main reason that many infectious diseases are difficult to control, and it is also a major source of pollution in the process of food processing. In the biofilm formation process, the quorum sensing system plays an important role. Based on the existing theory and research, the characteristics of bacterial biofilm and the role of population sensing system in bacterial biofilm formation were reviewed in order to provide a new study idea for the inhibition of biofilm formation by population induction inhibitors.
