摘要
后生素是指由对宿主健康有益的无生命的微生物和/或菌体成分/代谢物组成的制剂.有效的后生素,必须包含无生命的微生物细胞或菌体成分,且菌体成分主要包括细胞壁、细胞膜、脂磷壁酸、脂多糖、细胞外囊泡、菌毛和细胞表层蛋白等.本文从后生素调节肠道菌群、增强肠道屏障功能、调节免疫反应、调节机体代谢和调节神经传导等五个方面的益生功能综述其作用机制,并总结了乳杆菌源、酵母源等不同来源的后生素在动物中的应用,以期为后生素后续的分类、开发和利用提供参考.
Abstract
Postbiotics are the preparation of inanimate microorganisms and/or their components/metabolites that confer a health benefit on the host.Effective postbiotics must contain inactivated microbial cells or cell components,and cell components mainly include cell walls,cell membranes,lipoteichoic acid,lipopolysaccharides,extracellular vesicles,pilus and cell surface protein.In this paper,the mechanism of action of postbiotics is reviewed from five aspects of probiotic functions such as regulation of intestinal flora,enhancement of intestinal barrier function,regulation of immune response,regulation of body metabolism and regulation of neurotransmission,etc.,and the application of different sources of postbiotics such as Lactobacillus source and yeast source in animals is also summarised,intending to provide a reference for the subsequent classification,development and utilization of postbiotics.
