Abstract: The balance of intestinal flora plays an important role in human health and disease prevention. Prebiotics are the most promising health foods because they can regulate the structure and number of intestinal flora. Mushroom extract can significantly modify intestinal flora composition, which reveals the promotion roles in the metabolism and proliferation of beneficial microorganisms such as Lactobacilli and Bifidobacteria, as well as the inhibitory effect on pathogenic bacteria such as E. coli, Clostridium and Salmonella. The major components with prebiotic function in mushroom are non-digestible polysaccharides.

Key words: mushroom, intestinal flora, prebiotics, probiotics, polysaccharides
