Effect of Enzymatic Treatment on Alkaline Delignification of Wheat Straw |
| |
| Abstract: | Wheat straw was treated with crude enzyme from Aspergillus niger An76 prior to alkaline delignification of wheat straw, and effect of treatment conditions (enzyme dosage, treatment time and washing methods) in enzymatic treatment stage on alkaline delignification were studied. The effect of enzyme treatment on physical properties of chemical pulps was also researched. The results show that enzyme treatment prior to alkaline delignification can improve alkaline delignification of wheat straw, decrease alkali consumption during chemical cooking, and improve ISO brightness and strength properties of pulps. |
