Patent ID: 8518684

Claim:
An enzyme composition comprising a CEL6 polypeptide having cellobiohydrolase II activity, a GH10 polypeptide having xylanase activity, and one or more cellulolytic enzymes selected from the group consisting of an endoglucanase, a cellobiohydrolase, and a beta-glucosidase, wherein one or both of the CEL6 polypeptide having cellobiohydrolase II activity and the GH10 polypeptide having xylanase activity are foreign to the one or more cellulolytic enzymes, wherein the CEL6 polypeptide having cellobiohydrolase II activity is selected from the group consisting of: (a) a polypeptide having cellobiohydrolase II activity comprising an amino acid sequence having a sequence identity of at least 90% to the mature polypeptide of SEQ ID NO: 30; (b) a polypeptide having cellobiohydrolase II activity encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 29 or the full-length complement thereof, wherein the very high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide for 12 to 24 hours and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 70° C.; (c) a polypeptide having cellobiohydrolase II activity encoded by a polynucleotide comprising a nucleotide sequence having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 29 of at least 90%; and (d) a polypeptide having cellobiohydrolase II activity comprising the mature polypeptide of SEQ ID NO: 30; and wherein the GH10 polypeptide having xylanase activity is selected from the group consisting of: (a) a polypeptide having xylanase activity comprising an amino acid sequence having a sequence identity of at least 90% to the mature polypeptide of SEQ ID NO: 70; (b) a polypeptide having xylanase activity encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 69 or the full-length complement thereof, wherein the very high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide for 12 to 24 hours and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 70° C.; (c) a polypeptide having xylanase activity encoded by a polynucleotide comprising a nucleotide sequence having a sequence identity of at least 90% to the mature polypeptide coding sequence of SEQ ID NO: 69; and (d) a polypeptide having xylanase activity comprising the mature polypeptide of SEQ ID NO: 70.
