Patent ID: 7494798

Claim:
An isolated polypeptide having cellulose 1,4-beta-cellobiosidase activity, selected from the group consisting of: (a) a polypeptide having cellulose 1,4-beta-cellobiosidase activity comprising an amino acid sequence having at least 95% identity with the amino acid sequence of SEQ ID NO: 5979; and (b) a polypeptide having cellulose 1,4-beta-cellobiosidase activity encoded by a gene comprising a nucleotide sequence which hybridizes under high stringency conditions with the nucleotide sequence of SEQ ID NO: 1782, or the full-length complementary strand thereof, wherein 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, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.
