果胶复合酶的生产及其在亚麻脱胶中的应用


打开文本图片集

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 22 h,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 retting-condition was determined. Under these optimal conditions, the retting-period can be reduced to 22 h, the weight-decreasing ratio was the same as the natural-retting, and the enzyme liquor could be recycled by four times.

亚麻是重要的纺织原料作物,亚麻纤维制品吸湿散热快、透气性好、挺括,广泛用于服装服饰等行业,颇受消费者的喜爱。(剩余3438字)
