Abstract:

In this paper, the influence of xylanase treatment on wheat straw pulp was investigated. The results indicate that the the surface morphology and chemical composition of xylanase treatment may change the surface morphology and chemical composition of wheat straw pulp, soften the pulp fiber and roughen the fiber surface with obvious crackles and flakes. Moreover, the ESCA and SEM results show that the lignin coverage on the pulp surface increases after the xylanase treatment, and that the coverage also increases with the dosage of xylanase.

Key words: xylanase, wheat straw pulp, surface morphology, chemical composition
