Xylo-oligosaccharides and ethanol preparation from bamboo processing residues were investigated. The bamboo xylan was selectively degraded by endo-xylanase to produce xylo-oligosaccharides. Xylan extraction residue was used for ethanol production through saccharification and fermentation processes. The xylan of bamboo processing residues was extracted with 7% Na OH solution for 1 h,the xylan extraction yield was 57. 81%. The xylan was hydrolyzed by endoxylanase with the dosage of 25 U / g xylan for 12 h,the...
