Effects of Flammulina velutipes polysaccharide on immune response and intestinal microbiota in mice

A crude polysaccharide derived from Flammulina velutipes (FVP), mainly consisting of glucose linked with β-glycosidic bonds, was administered to 6 week-old male ICR mice by gavage for five weeks, to investigate the effects on mice intestinal microbiota and immune response. The pH of the intestinal compartments decreased while short chain fatty acids concentrations increased in FVP-fed groups, in a dose dependent manner. High throughput...
