Improvement of alkaline method for obtaining arabinoxylan and lignocellulose. Higher temperature, lesser chemicals and shorter time in the efficient extraction. Arabinoxylan and lignocellulose extracted in high level from sugarcane bagasse. Efficient arabinoxylan hydrolysis for XOS or xylose obtaining by xylanases. XOS or xylose produced from arabinoxylan depend on fungal xylanase.
