Effects of Culture Medium Conditions on Intracellular Polysaccharides of Grifola frondosa

YI Ming-hu

Abstract

The effects of carbon source, nitrogen source, inorganic salts on the production of intracellular polysaccharide of Grifola frondosa were studied by orthogonal test. The results showed that the optimal culture medium contained 2.0% corn powder, 0.3% soybean powder and 0.15% KH2PO4. Under this condition, the yield of intracellular polysaccharides was 13.036 mg / 100 mL, 121.7% higher than that before optimization.
