1. A process for degrading a cellulosic material, comprising: treating the cellulosic material with an enzyme composition in the presence of a GH61 polypeptide having cellulolytic enhancing activity selected from the group consisting of: (a) a GH61 polypeptide having at least 80% sequence identity to the mature polypeptide of SEQ ID NO: 2 or SEQ ID NO: 4, or at least 93% sequence identity to the mature polypeptide of SEQ ID NO: 6; (b) a GH61 polypeptide encoded by a polynucleotide that hybridizes under at least very high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 3, SEQ ID NO: 5, SEQ ID NO: 7, SEQ ID NO: 8, or SEQ ID NO: 9, (ii) the cDNA sequence of SEQ ID NO: 1 or SEQ ID NO: 3, or (iii) the full-length complement of (i) or (ii); (c) a GH61 polypeptide encoded by a polynucleotide having at least 80% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 3, SEQ ID NO: 7, or SEQ ID NO: 8, or the cDNA sequence of SEQ ID NO: 1 or SEQ ID NO: 3, or at least 93% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 5 or SEQ ID NO: 9; (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 GH61 polypeptide of (a), (b), (c), or (d) that has cellulolytic enhancing activity. |
