摘要
通过时冬虫夏草菌（ＣｏｒｄｙｃｅｐｓＳｉｎｅｎｓｉｓ）的深层发酵条件如ｐＨ、培养温度、接种量及转速的探讨及对深层发酵培养基碳氮源和无机盐的筛选，确定了其深层培养所需条件及最佳碳氮源和无机盐。实验结果表明：冬虫夏草菌深层发酵的最适培养条件应为２４℃、２００ｒ／ｍｉｎ、ｐＨ５．０左右，接种量５～１５％，菌丝生长的最佳碳源为葡萄糖，最佳氮源为蛋白和氨基酸复合粉，最佳无机盐为磷酸二氢钾、硫酸镁和氯化钙。
The fermented conditlons and the optimurn carbon sources, nitrogen sources and inorganic saltwere studied by studying the fermentation of Cordyceps sinensis Sacc. The results showed that the optimumfermented conditions of Cordyceps sinensis Sacc are 24℃, 200r/min, pH5.0, inoculum quantity 5～15%.The optimum carbon source is glucose,the optimum nitrogen sources are peptone and amino acid powder,the optimum inorganic salt is KH2PO4,MgSO4 and CaCl2.
