Patent ID: 7771983

Claim:
An isolated polypeptide having cellulolytic enhancing activity, selected from the group consisting of: (a) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to the mature polypeptide of SEQ ID NO: 2; (b) a polypeptide encoded by a polynucleotide that hybridizes under high stringency conditions with (i) the complement of the mature polypeptide coding sequence of SEQ ID NO: 1, or (ii) the complement of the cDNA sequence contained in the mature polypeptide coding sequence of SEQ ID NO: 1, wherein high stringency conditions are defined as hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.; and (c) a polypeptide comprising or consisting of the amino acid sequence of SEQ ID NO: 2; or a fragment thereof having cellulolytic enhancing activity.
