摘　　要：文章介绍了以黑曲霉HYA4为菌种,采用固体发酵方法生产果胶复合酶的方法。通过测定脱胶过程中果胶酶、半纤维素酶活力及脱胶周期,确定脱胶的适宜条件。工艺优化后脱胶周期可缩短至22h,麻茎失重率与温水脱胶的相当,脱胶液可重复利用4次。This article discussed the production of the pectin compound enzyme by solid state fermentation with aspergillus niger HYA4. By detecting the activity of pectinase and hemicellulase and the retting-period, the optimal rettingcondition was determined. Under these optimal conditions, the retting-period can be reduced to 22 h, the weightdecreasing ratio was the same as the natural-retting, and the enzyme liquor could be recycled by four times.
