Study on the Fermentation Culture and Purification of Grifola frondosa Mycelia
After 14 days of Grifolafrondosa seed culture,the maximum value of the biomass and polysaccharide content is 8.0,1.4 g/L on the 90 hours fermentation,respectively.GF is isolated and purified from the mycelium of Grifola frondosa,and the water soluble polysaccharide fractions are obtained by Sepadex G200 column chromatography.The GF is homogeneous.
