采用9种不同的5%多元醇添加到酸性纤维素原酶中形成复合酶，分别在50℃、pH值4.8和6.8条件下，测定其对纤维素原酶的各种活力的影响，并把几种酶的样品在50℃、pH值4.8条件下用于棉针织物的抛光处理。结果表明，山梨醇对酶的活力有一定的提升效果，以5%的添加量最佳；1，3丙二醇，1，4丁二醇，聚乙二醇400，聚乙二醇6000的酶解作用最强，乙二醇、木糖醇、山梨醇的除毛效果最好；几种多元醇均可提高纤维素原酶的热稳定性。

In this article, complex enzymes are made by adding nine kinds of 5% polyhydric alcohols to acidic cellulose enzymes. The effects of polyhydric alcohols on cellulase activity are tested under pH 4.8 and 6.8 respec-tively at 50 ℃. Then polishing treatment is done to cotton knitted fabrics by using the made complex enzymes re-spectively. The results show that sorbitol has enhancement effect on cellulase activity, while adding 5% dosage of it reaching the best effect; 1,3 propanediol, 1,4 butanediol, polyethylene glycol 400 and polyethylene glycol 6 000 have strong effect on enzymolysis; and when adding ethylene glycol, xylitol or sorbitol to cellulase, the complex enzymes will have good polishing effect; and thermostability of cellulase are improved by several polyhydric alco-hols.
