Optimization of Culture Medium for Shaking Flask of Cordyceps militaris |
| |
| Abstract: | Objective]To optimize culture medium for shaking flask of Cordyceps militaris.Method] Using mycelium dry quality as the index.First,the best carbon and nitrogen source suitable for mycelia growth was selected by single factor test.Then,the optimum ratio of carbon source and nitrogen source,inorganic salt and VB1 was optimized by orthogonal experiment.Result] The optimum shaking flask medium for Cordyceps militaris was as follow:sweet potato 50 g/L,soluble starch 10 g/L,beef paste 10 g/L,yeast extract 10 g/L,KH2PO4 1.5 g/L,MgSO4 · 7H2O 1.0 g/L,VB1 0.10 g/L,pH natural.The dry weight of mycelia produced by this formula can reach 36.33 g/L.Conclusion]The optimizing culture medium for shaking flask of Cordyceps militaris can provide basic data for subsequent research and production. |
