Zusammenfassung:The invention discloses a method for preparing and producing internal cutting type xylanase for low polyxylose by an organism fermentation method by using industrial wastes as raw materials. The preparation method of internal cutting type xylanase comprises the following steps: sieving to obtain a Streptomyces rameus; using agricultural wastes which are processed by an alkaline method to generate internal cutting type xylanase; and purifying the internal cutting type xylanase by a biochemical method to obtain hydrolysable xylan so as to produce the internal cutting type xylanase of a low polyxylose product with low xylose content and a polymerization degree of 2 to 5.
