Abstract
The present invention relates to methods for degrading or converting a cellulosic material and for producing substances from the cellulosic material.
Claims20
A method for degrading or converting a cellulosic material, comprising:
- treating the cellulosic material with an enzyme composition in the presence of a chitin binding protein and a GH61 polypeptide having cellulolytic enhancing activity, wherein the chitin binding protein is selected from the group consisting of:
- (a) a chitin binding protein having at least 90% sequence identity to the full-length or mature chitin binding protein of SEQ ID NO:
- 4;
- and (b) a chitin binding protein encoded by a polynucleotide having at least 90% sequence identity to the full-length or mature chitin binding protein coding sequence of SEQ ID NO:
- 3;
- wherein the chitin binding protein and the GH61 polypeptide having cellulolytic enhancing activity act synergistically in stimulating the degrading or converting of the cellulosic material by the enzyme composition according to the following formula with a ratio greater than 1:
