摘　　要：以黑曲霉ＡＳ３４３０９为试验菌株，采用正交试验的方法，对利用酒精糟液生产糖化酶发酵工艺条件进行了研究和分析。得出一组最优摇瓶发酵培养基配方，并建立了各因素线性回归方程。该研究是减轻酒精废糟液处理负荷及其对环境的污染、节约糖化酶生产原料及用水，降低生产成本的一条有效途径，具有较高的工业推广价值。The fermentative conditions for producing glucoamylase from the waste liquid of grain stillage were studied and analyzed by means of orthogonalizing process,taking aspergillus niger 3.4309 as testing strain. An optimal formula of medium for shake culture was got and the linear regression equation considered various factors was build up.The study provides an effective approach for decreassing the load of treating waste liquid of grain stillage,reducing environment pollution,reducing the raw materials and water consumption of glucoamlyase production and cutting down the cost of production. So it is a valuable channel to spread in the industries.
