摘　　要：研究了麦草烧碱-AQ浆漆酶与木聚糖酶协同漂白效果。结果表明,在漆酶/介体体系漂白前进行木聚糖酶处理,可以明显改善浆料的可漂性,提高漆酶/介体漂白的脱木素率。纤维的SEM观察表明,经木聚糖酶处理的浆纤维更为柔软润胀。经OXLQP漂白后,浆料白度可达83.7%ISO,同时浆料有较好的强度。LMS and xylanase synergetic biobleaching of wheat straw NaOH-AQ pulp was investigated in this paper.The results showed that xylanase treatment could improve the bleachability and increase the delignification of the following LMS bleaching.The SEM observation indicated that the xylanase could improve the fibers swelling and softening.The brightness of the pulp bleached by synergetic bleaching sequence OXLQP reached83.7%ISO and the bleached pulp had good strength properties.
