在酸性纤维素酶液中分别加入1%(对溶液质量)的硫脲、硫氰酸钠、亚硫酸钠、亚硫酸氢钠、焦亚硫酸钠、连二亚硫酸钠、硫氢化钠、硫化钠等8种不同的硫化物,在温度40、50、60℃,pH=4.5、5.0、5.5的条件下,根据中心复合试验设计方案测定滤纸酶活力,并用Minitab软件分析各种硫化物对纤维素酶活力的影响.在相同的条件下对纯棉针织物进行酶处理,测定处理前后织物的顶破强力、毛羽去除率、处理残液葡萄糖含量来评价对织物的实际作用效果.结果表明,硫化物的加入可以小幅提高纤维素酶活力、扩大酶的温度和pH作用区间,但除了亚硫酸钠和连二亚硫酸钠外,其他6种硫化物的加入反而降低了织物的除毛效果.

1%(on the mass of acid cellulase solutions) of thiourea, sodium thiocyanate, sodium sulfite, so-dium bisulfite, sodium metabisulfite, sodium hyposulfite, sodium hydrosulfide and sodium sulfide were added to acid cellulase solutions, respectively. The filter paper enzymatic activities were measured according to cen-tral composite experiment design under 40, 50, 60 ℃ and pH 4.5, 5.0, 5.5. The effects of various sulfides on the enzymatic activities were analyzed by Minitab software. The cotton knitted fabrics were treated with cellu-lase under the same conditions, and the bursting strength, hairiness removal percentage and glucose content of residue liquid were measured to evaluate the practical performance on cotton fabrics. The results showed that the addition of sulfides could slightly enhance the cellulase activity, and widen cellulase working tempera-ture and pH range. However, except sodium sulfite and sodium hyposulfite, the addition of other six sulfides decreased the hairiness removal ability.
