Patent ID: 7226773

Claim:
An isolated polypeptide having cellulase activity, selected from the group consisting of: (a) a polypeptide encoded by a nucleic acid sequence with hybridizes with SEQ ID NO. 1 carried out in 2×SSC (Sambrook, 1989), 5× Denhardt's solution (Sambrook, 1989), 0.5 % (w/v) SDS, 100 micrograms/ml denatured salmon sperm DNA for 20 h at 65° C. followed by washes in 5×SSC at 25° C. (2×15 mm), 2×SSC, 0.5% SDS at 65° C. (30 min), 0.2×SSC, 0.5% SDS at 65° C. (30 mm) and finally in 5×SSC (2×15 min) at 25° C.; (b) a polypeptide having an amino acid sequence which has a degree of identity of at least 90% with SEQ ID NO: 2, wherein the degree of identity is determined by means of GAP provided in the GCG program package using settings of a GAP creation penalty of 3.0 and GAP extension penalty of 0.1; and (c) a fragment of SEQ ID NO: 2 having cellulase activity.
