香菇液态深层发酵工艺研究

香菇菌Nb—42菌丝最适液态生长温度为25℃，最适发酵时间为96h，最适振荡转速为200r／min，最适摇瓶装液量为60ml。乳化剂吐温－80使用量为0.8％，分散剂玻璃珠为了15粒时均可获得最高菌丝体重。经正交实验筛选出最佳液态发酵培养基：2％玉米粉、1.0％豆粕粉、0．1％酵母膏、0．5％葡萄糖的黄豆芽液。

The optimum growth temperature.fermantation time,vibration velocity and fermantation liquid contentsof Lentinus edodes showed 25℃,96h.200rpm,and 60ml,respectively.The emulsion of 0.8% Toween-80 or 15 pearl ofglass bead got also the optimum yield of hypha.The optimum liquid medium seleted with Lg(3)4 test method revealeda juice of beau sprout containing 2% maize powder, 1 .0% beau powder with free lipe.0. 1 % yeast extracted and 0.5%glucose.
