中文摘要: 该文综述乳酸菌(lactic acid bacteria,LAB)生物膜的结构组成(胞外多糖、细胞外DNA、蛋白质)、形成过程及其在应对环境胁迫中的保护作用,重点解析群体感应(quorum sensing,QS)信号分子通过调控基因表达和代谢重编程促进生物膜形成的分子机制。此外,探讨促进生物膜形成的策略(碳源调控、封装技术、共培养),以期为提升LAB在食品发酵中的稳定性提供理论依据和技术方向,进而优化传统发酵工艺,开发新型发酵制剂,推动食品工业中微生物发酵技术的创新应用与可持续发展。
Abstract:This paper reviewed the structural components (extracellular polysaccharides, extracellular DNA,and proteins), formation process, and protective role of lactic acid bacteria (LAB) biofilms against environmental stress. It also specifically elucidated the molecular mechanisms by which quorum sensing(QS) signaling molecules promote biofilm formation through gene expression regulation and metabolic reprogramming. Additionally, strategies to enhance biofilm formation (carbon source regulation, encapsulation technology, and co-culture) were discussed, aiming to provide a theoretical basis and technical direction for stability improvement of LAB in food fermentation. This further optimizes traditional fermentation processes and develops novel fermentation agents, promoting innovative applications and sustainable development of microbial fermentation technology in the food industry.
