| 摘 要： | 研究了卷须链霉菌 (Streptomycescirratus)D 1 0木聚糖酶水解玉米芯汽爆液的酶用量和水解时间 ,结果得到 80U/ 1 0 0mL酶用量和水解 6h是合适的加酶量和水解时间 ;筛选出 1株能够精制低聚木糖的Candiasp .酵母 ,该酵母能消耗木糖、阿拉伯糖而不消耗木二糖 ;利用此酵母精制酶解液 ,在接菌量为 1 0 %,48h时酶解液中木糖、阿拉伯糖完全被消耗 ,木二糖以上的低聚木糖含量变化不明显 ,因此利用该酵母能达到精制低聚木糖的效果

| Abstract: | The conditions of Streptomyces cirratus D 10 xylanase hydrolyzing steam exploded corncob were studied.It shows that the proper amount of xylanase and the appropriate hydrolyzed time were 80U/mL and 6h,respectively. A strain of Candia sp. was selected in this study. This strain can effectively and selectively metabolize all xylose and arabinose but not xylobiose,so it could be used to purify the hydrolyzed steam exploded corncob. Xylose and arabinose in the hydrolysate were fully consumed with 10% inoculum at 48h,while the mount of the xylooligosaccharides unchanged. |
