| Abstract: | The liquid fermentation for mycelium production by Flammulina velutipes is studied in this paper. The orthogonal and single-factor experiments are adopted to explore the influence of ingredients of medium and cultural conditions on the yielding biomasses of mycelia from Flammulina velutipes. The experimental results show that the compositions of optimal medium are as fellows： 40 g/L soybean flour, 20 g/L soluble starch,2 g/L KH2PO4 and 1 g/L MgSO4·7 H2O. The dry biomasses can reach maximum production with inoculated volumes 200 mL/L,culture volumes 400 mL/L,pH6.0,160 r/min,temperature 25 ℃,and cultivation eight days. The effective culture process for the high production of Flammulina velutipes in liquid fermentation is obtained with optimal medium and culture conditions. |
