摘要:
对棉籽壳酶法生产低聚木糖的工艺参数进行优化。采用响应面法优化了预处理时间、盐酸溶液质量分数和酶解pH值,得到最佳工艺条件为:预处理时间35.70 min、盐酸溶液质量分数0.17%、酶解pH 6.5。在此条件下,木二糖质量浓度达到14.52 g/L,与模型预测值基本相符。且低聚木糖以木二糖为主,木二糖得率为8.13%(以棉籽壳干质量计)。
关键词: 棉籽壳, 低聚木糖, 木二糖, 响应面法
Abstract:
The enzymatic hydrolysis of cotton seed husk with xylanase for xylo-oligosaccharides production was optimized by response surface methodology in this research. A pretreatment time of 35.70 min with 0.17% HCl was found optimal for the enzymatic hydrolysis, which was performed at an initial pH of 6.5. At the end of the hydrolysis, the concentration of xylobiose in hydrolysis was measured to be 14.52 g/L, agreeing with the predicted value. The final product was mostly xylobiose with a yield of 8.13% (relative to the dry weight of cotton seed husk).
Key words: cottonseed husk, xylo-oligosaccharides, xylobiose, response surface methodology
