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,探讨酶改性温度、pH值、酶用量、介体用量、酶改性时间对纸浆强度性能、白度及紧度的影响。结果表明,LMS处理后纸浆可漂性提高,白度提高7.59%ISO;纸页抗张强度和撕裂强度得到明显改善,同时紧度也得到一定程度的提高。The bagasse unbleached TMP was treated with laccase toge ther with a mediator and there after bleached with hydrogen peroxide （H2O2） .The influence of such factors as enzyme treatment temperature, pH value, enzyme dosage, mediator dosage and enzyme treatment time on the pulp whiteness, density and strength were analyzed in this paper. At the optimum conditions, the TMP brightness increased 7.59%ISO compared to the sample pulp; the tensile index, density and the tear index also increase visibly.
