摘要
采用DNS法研究了超声波条件下中性纤维素酶的活性,探讨超声波处理功率、中性纤维素浓度、处理温度、pH值及处理时间对中性纤维素酶活性的影响,并对优化后的超声波处理工艺条件下的牛仔布的褪色性能进行了测试.结果表明：适当的超声波处理能提高中性纤维素的活性,超声波协同中性纤维素酶活性达到最佳效果的工艺条件是超声功率为200 W,中性纤维素酶质量浓度为2 g/L,温度为55~60℃,pH值为5,时间为15~25 min;经超声波协同纤维素酶整理的牛仔布的退色情况较仅用酶整理的牛仔布的退色情况有所增强,退色率提高了14.1%.
The activity of neutral cellulose enzyme in ultrasonic condition were measured by using DNS method, and the various factors affecting the activity of neutral cellulose enzyme such as power of ultrasonication, concentration of neutral cellulose enzyme, temperature, pH value and processing time were studied. And the fade performance of denim through the treatment which was under the optimal conditions were discussed. The results indicate that the ultrasonic energy during enzymatic treatment results in improvement in activity of neutral cellulose enzyme, the optimal conditions of combination of ultrasound with conventional enzymatic treatment of denim are at ultrasonic power 200 W, concentration of enzyme 2 g/L, temperature 55-60 ℃, pH value 5, and porcessing time 15-25 rain. The fading rate of denim after introduction of ultrasonic energy during enzyme wash is increased by 14.1% compared with which is treated only by neutral cellulose enzyme.
