【摘要】 为了探索蛹虫草液体发酵中适合虫草素积累的培养基和发酵培养条件,以半定量薄层色谱法为检测手段,以虫草素含量为指标,通过单因素试验及正交试验优选的方法,最终优选出的培养基配方为蛋白胨15 g.L-1、葡萄糖20 g.L-1、磷酸二氢钾1 g.L-1、七水合硫酸镁0.5 g.L-1、维生素B1 10 mg.L-1、萘乙酸2 mg.L-1。优选出的培养条件为发酵液pH7,培养温度25℃,光照时间12 h。
【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 m...
