摘要
在草浆酶改性过程中 ,以纤维素酶为主的酶系对草浆滤水性能的改善是必需的 ,而木聚糖酶对草浆滤水性能的改善起到了辅助作用。纤维素酶酶系中含有相对较低的木聚糖酶活和较高的FPA活力时 ,浆的滤水性能改善更加明显。在酶改性处理剂量范围内 。
Concerning enzymatic modification of straw pulp. It was found that the cellulase systems were necessary in order to improve the drainage behavior bleached wheat straw pulp, while xylanases played an assistant role. The pulp drainage could be significantly improved with lower X'ase/CMC'ase ratio and higher FPA/CMC'ase ratio in the cellulase systems. At the enzyme charge for modification of the pulp, the enzyme treatment had no substantial effect on the strength properties of the pulp.
