摘要

The present invention relates to methods for degrading or converting a cellulosic material and for producing a substance from a cellulosic material.

主权项

1. A method for degrading or converting a cellulosic material, comprising: treating the cellulosic material with a recombinant host cell transformed with a nucleic acid encoding an enzyme composition comprising a GH61 polypeptide having cellulolytic enhancing activity and recovering the degraded or converted cellulosic material, wherein the GH61 polypeptide having cellulolytic enhancing activity is selected from the group consisting of:
(a) a GH61 polypeptide having at least 95% sequence identity to amino acids 22 to 320 of SEQ ID NO: 2; (b) a GH61 polypeptide encoded by a polynucleotide having at least 95% sequence identity to nucleotides 64 to 1018 of SEQ ID NO: 1 or nucleotides 64-101 and 160-1018 of SEQ ID NO: 1; and (c) a fragment of the GH61 polypeptide of (a) or (b) that has cellulolytic enhancing activity.
