嗜热真菌木聚糖酶与稀酸联合水解甜菜渣生产L-阿拉伯糖的初步研究
Journal of South-Central University for Nationalities(Natural Science Edition)（2009）
Abstract
通过嗜热真菌DSM 10635固体发酵生产木聚糖酶,探讨了利用该木聚糖酶-稀酸联合水解甜菜渣生产稀少五碳糖的方法,并对水解产物进行了定量分析.研究发现:通过木聚糖酶-稀酸水解甜菜渣可得到稀少单糖,主要有阿拉伯糖、葡萄糖、木糖等.HPLC结果显示:甜菜渣的水解产物中L-阿拉伯糖含量占全部单糖含量的48.4%(质量分数).实验结果为进一步研究L-阿拉伯糖的工业生产和精制奠定了基础.
