白灵菇深层培养工艺的研究

Study on Submerged Culture Technology of Pleurotus ferulae

通过对白灵菇进行深层培养工艺的研究 ,发现白灵菇菌丝体生长的液体培养基的最适配方为 :玉米粉 5 % ,蔗糖 1 % ,KH2 PO40 .3 % ,MgSO4·7H2 O 0 .1 5 % ,VB11 0mg/L ,α 淀粉酶 0 .1 %。在pH 6.0 ,2 5℃的培养条件下菌丝体生长最佳。

By submerged culture experiment of Pleurotus ferulae,the authors found the optimum liquid medium.Composition of the medium consists of 5.0% cornmeal,{1.0%} sucrose, 0.3% KH-2PO-4, 0.15% MgSO-4·7H-2O, 0.2% yeast paste,{0.1%} α-starch enzyme and VB-1 10mg/L. Under conditions of pH 6.0, 25℃,the biomass of mycelia reached the highest level.
