摘　　要：以玉米芯为原料,通过酸水解、微生物发酵除杂、重结晶等步骤制备L-阿拉伯糖晶体的方法。用浓度为6%的H_2SO_4溶液在100℃下使玉米芯水解2.5 h,再在水解液中接入球拟酵母菌30℃下发酵3 d,除去葡萄糖和木糖。最后,经活性炭脱色和离子交换树脂脱离子后,浓缩发酵液,重结晶制得1.03 g L-阿拉伯糖晶体。The preparation method of L-arabinose from comcobs by acid hydrolysate, microbial fermentation, recrystallization was reported. The corncobs were hydrolysised by 6% H2SO4 solution 2.5 h under 100℃, and the ball yeast was aerobically cultured in the hydrolyzed solution for 3 d to ferment remove xylose and glucose. The 1.03 g L-arabinose crystalline was obtained after decolorized with active carbon, desalted with exchange resins, concentrated, and then recrystallization.
