摘　　要：研究了漆酶NS51003/介体体系(LMS)改性对未漂马尾松TMP性能的影响,探讨了酶改性温度、pH值、酶用量、介体用量、酶改性时间对纸浆强度性能、白度及松厚度的影响。结果表明:LMS处理后纸浆可漂性提高,白度提高3.80%ISO;纸页抗张强度、撕裂强度、耐破强度均得到明显的改善,同时松厚度也得到一定程度的提高。It was studied that the masson pine unbleached TMP was treated with laccase together with a mediator and thereafter bleached with hydrogen peroxide（H2O2）.The influences of such factors as enzyme treatment temperature, pH value, enzyme dosage, mediator dosage and enzyme treatment time on the pulp whiteness, bulk and strength were analyzed in this paper. The result showes that at the optimal conditions, the TMP brightness is increased by 3.11%ISO compared to the sample pulp; the tensile index, bulkness and the tear index are also increased to a certain extent.
