Polypeptides Having Beta-Xylosidase Activity and Polynucleotides Encoding Same

An isolated polypeptide having beta-xylosidase activity, selected from the group consisting of:

• (a) a polypeptide having at least 60% sequence identity to the mature polypeptide of SEQ ID NO:
• 2 or SEQ ID NO:
• 4;
• or at least 80% sequence identity to the mature polypeptide of SEQ ID NO:
• 6;
• (b) a polypeptide encoded by a polynucleotide that hybridizes under at least medium-high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO:
• 1 or SEQ ID NO:
• 3, (ii) the cDNA sequence of SEQ ID NO:
• 1 or SEQ ID NO:
• 3, or (iii) the full-length complement of (i) or (ii);
• or under at least high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO:
• 5 or the full-length complement thereof;
• (c) a polypeptide encoded by a polynucleotide having at least 60% sequence identity to the mature polypeptide of SEQ ID NO:
• 1 or SEQ ID NO:
• 3, or the cDNA sequences thereof;
• or at least 80% sequence identity to the mature polypeptide of SEQ ID NO:
• 5;
• (d) a variant of the mature polypeptide of SEQ ID NO:
• 2, SEQ ID NO:
• 4, or SEQ ID NO:
• 6 comprising a substitution, deletion, and/or insertion at one or more positions;
• and
• (e) a fragment of the polypeptide of (a), (b), (c), or (d) that has beta-xylosidase activity.
