| 摘 要： | 研究了漆酶和漆酶/介体体系处理对三倍体毛白杨APMP性能的影响.采取酶解-弱酸解两段法分别从APMP原浆和生物处理后的纸浆中分离木素.为了使木素在凝胶渗透色谱流动相四氢呋喃中能完全溶解,对所有试样进行了卞基化处理.利用凝胶渗透色谱分析仪获得了木素的分子质量分布曲线,并计算出数均分子质量和质均分子质量,进而比较了漆酶和漆酶/介体体系处理的效果和差异. |

| Abstract: | The alkaline peroxide mechanical pulps(APMP) of Triploid of Populus Tomentosa was treated by laccase and laccase-mediator-system(LMS) respectively,the factors affecting physical properties of the pulp were studied.The two-stage method of enzyme-mild acidic hydrolysis was adopted to isolate lignin from the APMP and the modified pulp samples.All the benzoylated lignin samples were dissolved in THF.The molecular weight distributions of lignins were obtained through GPC,the relative number average molecular wei... |
| Keywords: | lignin molecular weigh distributions laccase laccase-mediator-system APMP |
