银耳多糖益生元效应的研究

Study on the Prebiotic Effect of Tremella Fuciformis Polysaccharide

银耳是一种非常重要的食用菌和药用真菌,具有非常多的药理作用。本研究通过体外实验研究了银耳多糖的益生元效应,研究结果表明,银耳多糖能够促进双歧杆菌和乳酸杆菌的生长,且成剂量关系;0.5%的银耳多糖对青春双歧杆菌、长双歧杆菌婴儿亚种、嗜酸乳杆菌及鼠李糖乳杆菌的生长促进效果最显著;同时可以通过降低pH,提高B/E值,增强肠道有益微生物定植。

Tremella fuciformis is a very important edible fungus and medicinal fungus,which has many pharmacological effects.This study investigated the prebiotic effects of Tremella fuciformis polysaccharides through in vitro experiments.The results showed that Tremella fuciformis polysaccharides can promote the growth of bifidobacteria and lactobacilli,and there is a dose relationship;0.5%of Tremella fuciformis polysaccharides can affect Bifidobacterium adolescentis and Bifidobacterium longum.subsp.infantis,Lactobacillus acidophilus and Lactobacillus rhamnosus have the most significant growth-promoting effects;at the same time,it can reduce the pH,increase the B/E value,and enhance the colonization of beneficial intestinal microorganisms.
