生物膜(Biofilm)是由众多微生物聚集黏附在物体表面形成的多细胞群体结构,多种食源性微生物均能形成相应的生物膜,且该现象的产生对食品加工与安全有着重要影响。群体感应(Quorum sensing,QS)已被证明是调控生物膜形成的重要因素。文章主要介绍了群体感应对几种食源性细菌及真菌生物膜形成的调控作用,旨在为食品加工过程中微生物生物膜的控制与利用提供参考。
The biofilm is a multicellular group structure formed by numerous gathered microorganism which adheres on the surfaces.This phenomenon is widespread in a variety of foodborne micro-organism,and it is important for food processing and security.Quorum sensing(QS)has been proven to be an important factor in the formation of biofilm.In this review,the regulation function of QS in the biofilm formation of several kinds of foodborne bacteria and fungi was discussed,and this would provide reference to biofilm control and utilization in food processing.
