Research Progress on Mechanism and Application of Postbiotics in Regulating Animal Intestinal Health
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.
