摘要: 采用木聚糖酶对麦草浆进行处理,研究了木聚糖酶处理对麦草浆表面形态及化学组成的影响.发现酶处理可以改变麦草浆的表面形态及化学组成,酶处理后的麦草浆变得柔软,纤维表面变得粗糙,出现明显的裂隙和沟槽.ESCA、SEM分析结果表明:经木聚糖酶处理后,麦草浆表面木素含量提高;且随着木聚糖酶用量的增加,处理后的麦草浆表面木素的含量也随之增加.

关键词: 木聚糖酶, 麦草浆, 表面形态, 化学组成

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
