摘要： A xylanase gene, denoted xynR8, encoding a xylanase (XynR8) obtained from the unisolated rumen microorganisms is provided. The DNA sequence of the xynR8 gene, xylanase, is also provided, the enzyme is thermostable, and highly specific for xylans with high activity. Transformation of microbial hosts with the xynR8 gene is described. A method for degrading the xylan-containing structure comprises hydrolyzing the β-1,4-glycosidic bonds of xylans by contacting xylanase is provided, and a composition employing the above-mentioned hydrolyzing method is further addressed.
