| 摘 要： | 以纤维二糖作为纤维素的模型物,分析探讨了纤维二糖的碱性降解性能.从反应物和产物两方面进行探讨分析,即在不同金属离子条件下,纤维二糖的降解情况和产物葡萄糖的生成情况会有不同的表现.结果发现:K+促进纤维二糖的碱性降解;而Mg2+和Ca2+抑制了纤维二糖的碱性降解.

| Abstract: | The alkaline degradation of cellobiose which was taken as a fiber model was analysed.How metal ions affect the alkaline degradation of cellobiose was discussed from two aspects:the reactant and product,namely the cellobiose degradation and glucose production.The results showed that K+ promoted cellobiose’s alkaline degradation,while Mg2+ and Ca2+ suppress cellobiose’s alkaline degradation. |
