1. one kind has the active isolated polypeptide of acetyl xylan esterase, and it is selected from down group:

  • (a) comprise the polypeptide that has the aminoacid sequence of at least 75% identity with the mature polypeptide of SEQ ID NO;

    2;

    (b) by the polypeptide of following polynucleotide encoding, described polynucleotide under medium at least-Gao stringent condition with following hybridization;

    (i) the mature polypeptide encoded sequence of SEQ ID NO;

    1;

    (ii) be contained in the cDNA sequence in the mature polypeptide encoded sequence of SEQ IDNO;
