研究漆酶NS51003对未漂APMP浆性能的影响,探讨漆酶处理温度、时间及酶用量对纸浆白度及强度性能的影响。结果表明:在最佳的实验条件下漆酶处理可以提高纸浆的强度性能,白度稍有下降。漆酶处理主要作用于纤维表面的木素。
The effect of laccase NS51003 on the properties of unbleached APMP pulp was studied. The effects of laccase treatment temperature, time and enzyme dosage on pulp whiteness and strength were studied. The results showed that under the best experimental conditions, laccase treatment could improve the strength performance of pulp and the whiteness slightly decreased. Laccase treatment mainly affects the fiber surface lignin.
