transgenic microbial host cell, methods for producing a polypeptide, for degrading or converting a cellulosic material or xylan-containing material, for producing a fermentation product, for fermenting a cellulosic or xylan-containing material, nucleic acid constructs, and, expression vector

摘要

polypeptide, polynucleotide, method for making the polypeptide, for producing a mutant of a percus cell, for inhibiting expression of a polypeptide, for producing a protein, for degrading or converting a cellulosic material or xylan-containing material, for producing a fermentation product and to ferment a cellulosic material or material containing xylan, transgenic plant, plant part or transformed plant cell, and double stranded inhibitory RNA molecule. The present invention relates to isolated polypeptides having xylanase activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors and host cells comprising polynucleotides as well as methods for producing and using polypeptides.
