More Information
Summary:This invention involves a kind of enzymatic production method of xylose. The specific steps are pre-treat wasted crop to produce xylan or steam exploded substance; then add xylanase, bi-activity xylose/arabinosidase and alpha-glucuronidase to buffer to generate multi- enzyme mix liquid. Mixing it and adding the xylan or steam exploded substance to multi- enzyme mix liquid to perform enzymatic hydrolysis. After hydrolysis, adds ethanol to enzymatic hydrolysis liquid and further condese and crystallize to get xylose product. The release rate of xylose can reach as much as two times of using Xylanase and xylosidase so to increase the productivity. The power consuming is low. The product can keep the natural quality. At the same time the xylose produced with enzyme has no harm to microbial species, and can be used directly in biotransformation of xylitol by yeast. It is virus free and with good fermentation performance. It is benefical for the transformation from xylose to xylitol.
