摘　　要：分别用半纤维素酶PulpzymeHC、纤维素酶Novozym476对马尾松未漂磨石磨木浆(GP)进行预处理,然后再进行NS51003漆酶/介体系统生物酶处理及后续的H2O2漂白,并对酶处理浆在H2O2漂白前后白度和强度性能进行测定。研究结果表明,利用半纤维素酶PulpzymeHC、纤维素酶Novozym476对马尾松未漂磨石磨木浆(GP)进行预处理,可有效提高漆酶NS51003处理马尾松未漂GP的效率,更加有效的提高纸浆的白度及强度性能,而且适当的预处理可使纸浆具有更好的可漂性,从而使H2O2漂白后的酶处理浆具有更高的白度和更好的强度性能。The masson pine unbleached groundwood pulp(GP) was pretreated with Pulpzym HC or Novozym 476, (respectively), and then treated with laccase NS 51003 together with a mediator and thereafter bleached with hydrogen peroxide(H_2O_2). The results showed that the pretreatment of GP by Pulpzyme HC or Novozym 476 could improve the effect of treatment of laccase NS 51003, and improve the brightness and strength properties. Furthermore the treated pulp had a better bleachability and after it was bleached with H_2O_2,the treated pulp had a higher brightness and a better strength properties than the control pulp.
