Assay Study on Optimal Cultivation Conditions to Accumulate the Ganoderma Polysaccharide

Abstract

Abstract: The effects of carbon source,nitrogen source and pH to accumulate the Ganoderma polysaccharide were studied in this paper.The results showed that the optimal carbon source,nitrogen source and pH were sucrose, peptone and pH5.0 respectively. The optimal conditions were: KH2PO4 0.1, MgSO·7H2O 0.05 and (NH4)2SO4 0.2, peptone 0.3, sucrose 5 and 4 pH5.0.The concentration of Ganoderma polysaccharide in mycelia was 11.77%, 2.5 fold higher than that of the fruiting body and 2.2 fold higher than that of the spores.

Key words: Ganoderma lucidum, polysaccharide, liquid medium
