摘要
[目的]验证混合菌对竹笋壳的降解效果。[方法]运用红外光谱分析(IR)、气质联用(GC-MS)和扫描电子显微镜技术(SEM)对降解前后竹笋壳的成分和表面结构变化进行了分析。[结果]混合菌分泌的水解酶先降解竹笋壳表面的蜡质、半纤维素和纤维素,甲基化和氧化竹笋壳木质素侧链,随后破坏木质素苯环。[结论]竹笋壳表面硅结构的裸露程度可以作为竹笋壳降解程度的评价指标。
[ Objective ] The aim was to verify degradation process of bamboo shoot shell by mixed bacteria. [ Method] We analyzed the composition and surface structure of bamboo shoot shell before and after degradation by IR,GC-MS and SEM. [ Result] The hydrolytic enzymes secreted by mixed bacteria firstly degraded the wax,hemicellulose and cellulose of bamboo shoot shell surface, and methylated and oxidized the lignin side chain of bamboo shoot shell, and then destroyed the lignin benzene. [ Conclusion ] The bare degree of silicon structure of bamboo shoot shell sur- face could be taken as the evaluation index of bamboo shoot shell degradation degree.
