The present invention relates to isolated polypeptides having alpha-L-arabinofuranosidase activity and isolated nucleic acid sequences encoding the polypeptides, such that the nucleic acid is operably linked to a heteroloqous control sequence for expression. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid sequences as well as methods for producing and using the polypeptides set forth in SEQ ID NO:2 and fragments of SEQ ID NO:2.
