摘　　要：研究漆酶NS51003/介体体系(LMS)改性对未漂蔗渣TMP性能的影响,探讨不同酶用量对PFI磨磨浆能耗、成纸强度性能、白度及返黄的影响。结果表明,LMS处理后可以节约磨浆能耗,纸浆可漂性提高,白度提高6.5%ISO;纸页抗张强度、撕裂强度均得到明显的改善,同时紧度也得到一定程度的提高。Bagasse unbleached TMP was treated with laccase together with a mediator and thereafter bleached with hydrogen peroxide（H2O2） . The influences of enzyme dosage on the beating energy consumption, pulp brightness, PC number and strength were analyzed in this paper. At the optimum conditions, pretreatment with laecase before beating can reduce beating energy comsumption, the TMP brightness increases 6.5% ISO compared to the control pulp; the tensile index, density and tear index also increase.
