摘　　要：通过现代生物技术构建的产糖化酶酵母,在酒精生产过程中既能够高效产酒、又能够替代部分糖化酶。具有降低发酵体系中还原糖,稳定发酵酒份,抑制挥发酸,减少安菌泰的使用等优势,同时一定程度下,降低了酒精废水的COD值,减轻了环保压力。若我司按照糖化酶替代量50%计算,则年节约成本242万元。The using of yeast with the ability of expressing glucoamylase can increase alcohol content and reduce the addition of glucoamylase. This way can reduce the production of reducing sugar, stable fermented wine, inhibit volatile acids, and reduce the addition of Anjuntaiin in the fermentation system. Meanwhile, it reduces the COD value of alcohol wastewater and relieves the environmental pressure. If the replacement of glucoamylase reaches 50%, the annual cost savings is 2.42 million yuan.
