摘要
本文探讨了泰山赤灵芝(Ganodermalucidum)液体培养中碳源、氮源、pH对灵芝多糖积累的影响。结果表明,培养基最适碳源、氮源、pH值分别为蔗糖、蛋白胨、5.0,其配方组成(质量分数,%)为:KH2PO40.1,MgSO4·7H2O0.05,(NH4)2SO40.2,蛋白胨0.3,蔗糖5,pH5.0,灵芝多糖含量可达11.77%,分别是子实体和孢子粉的2.5和2.2倍。
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.
