摘要/Abstract

摘要： 为了提高棉织物中酶精练对非纤维素杂志的去除效果，考察了温度对酶精练催化效率的影响。发现,在一定温度范围内，精练时温度对各种酶催化效率影响重大，催化效率最高时的温度远高于酶的最适反应温度。通过研究不同温度时棉织物对碱性纤维素酶的吸附量、蜡质的熔点及蜡质含量对纤维素酶去除棉籽壳的效率的影响,分析认为这与棉纤维表层结构和化学组成有很大的相关性，并据此讨论了酶精练中温度对酶催化效率的影响机制。

Abstract: To improve the removal of non-cellulose impurities in cotton bio-scouring, effect of temperature on the catalytic efficiency of enzymes was investigated. It was found that temperature had great effects on the enzyme catalytic efficiency with in a certain scope of treatment temperature in cotton bio-scouring. The temperature for the best enzyme catalytic efficiency is much higher than the optimum temperature for cotton bio-scouring. Based on the analysis of the effects of temperature on the cellulase adsorption onto the cotton, of the melting points of the cotton waxes, and of the effects of the waxes on the removal of cotton seed coats for cellulase, the mechanism of temperature affecting enzyme catalytic efficiency in cotton bio-scouring was proposed.

Key words: cotton, enzymatic scouring, catalytic efficiency, temperature
