| Abstract: | To find out the best Cordyceps militaris fermentation medium and growth conditions for producing cordycepin,the composition of the culture medium,the culture temperature and light time were investigated by single factor experiment and orthogonal test.Half quantitative thin layer chromatography method was used to measure the concentration of the produced cordycepin.The results showed that the optimal culture medium were peptone 15 g·L-1,glucose 20 g·L-1,KH2PO4 1 g·L-1,MgSO4·H2O 0.5 g·L-1,VB1 10 mg·L-1,1-naphthlcetic acid 2 mg·L-1 and pH7.The best temperature was 25℃ and the light length was 12 h per day. |
