摘　　要：研究是在高浓度铁、锌、钙离子条件下,采用正交实验(大豆粉、玉米粉、蔗糖、磷酸二氢钾4因素)优化冬虫夏草生物活性强化剂液态发酵的生产条件,得出最佳培养基配比:大豆2%、玉米4%、蔗糖4%、KH2PO4 0.05%。同时探讨了在此配比下,耗氧量、起始pH值及培养时间对菌体产量的影响。The optimal medium for submerged culture bioactive supplement agent of cordyccys sinensis in high concentration Ca2+, Fe2+, Zn2+ ions were investigated in this paper. The optimal medium was established as follows: soybean 2%, corn 4%, sucrose 4%, KH2PO4 0.05%. Using this optimal medium, the relation between consuming oxygen quantity, primely pH value, culture time and hyphal growth rate was studied.
