| 摘 要： | INTRODUCTIONThe increasing consumption of paper and paper board all over the world and the more and more serious legislative constraints on forest resources intensify the shortage of pulping materials. Agricultural residues such as wheat straw are of increasing interests in countries and areas which have abundant plantation of agricultures and are lack of wood supply. One of the problems associated with the wheat straw pulp was the low pulp yield and low bleachability relative to wood pulp…

| Abstract: | Wheat straw chemi-mechanical pulp was pretreated with a crude xylanase which was secreted by white rot fungus Phanerochaete Chrysosporium prior to hydrogen peroxide bleaching. The process of xylanase pretreatment and hydrogen peroxide bleaching was optimized. The xylanase treated pulp achieved a brightness gain of 5.8% ISO over the untreated pulp. The xylanase treatment was found to liberate reducing sugars and facilitating lignin removal. Fiber morphology of pulp treated with xylanase was also studied by SEM. |
