比较了在相同的条件下 ,含盐和不含盐的底物、含木素和不含木素的底物、聚合度和糖基比不同的底物在木聚糖酶的作用下 ,定向制备木低聚糖时的木低聚糖得率、木糖得率、总糖得率 ,阐明了氯化钠、木素的存在以及木聚糖支链、木聚糖聚合度的差异对实验结果的影响。从而为制定木聚糖和木低聚糖的最佳生产工艺提供理论依据。 Comparing substrates containing salt and salt, lignin-containing and lignin-free substrates, substrates with different degrees of polymerization and glycosylation under the same conditions were oriented under the action of xylanase The yield of xylooligosaccharides, the yield of xylose and the yield of total sugar during the preparation of xylan were elucidated on the basis of the existence of sodium chloride and lignin and the differences in the degree of xylan branching and xylan polymerization Effect of the result. So as to provide the theoretical basis for making the best production process of xylan and xylooligosaccharides.
