Methods for enhancing the degradation or conversion of cellulosic material

A method for producing a fermentation product, comprising:

• (A) saccharifying a cellulosic material with an enzyme composition in the presence of a polypeptide having cellulolytic enhancing activity, wherein the polypeptide having cellulolytic enhancing activity is selected from the group consisting of:
• (a) a polypeptide comprising an amino acid sequence having at least 75% sequence identity with the mature polypeptide of SEQ ID NO:
• 2;
• (b) a polypeptide encoded by a polynucleotide that hybridizes under medium-high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO:
• 1, (ii) the cDNA sequence contained in the mature polypeptide coding sequence of SEQ ID NO:
• 1, or (iii) the full-length complementary strand of (i) or (ii);
• (c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 75% sequence identity with the mature polypeptide coding sequence of SEQ ID NO:
• 1 or the cDNA sequence thereof;
• and
• (d) a variant comprising a substitution, deletion, and/or insertion of one or more (several) amino acids of the mature polypeptide of SEQ ID NO:
• 2;
• (B) fermenting the saccharified cellulosic material with one or more (several) fermenting microorganisms;
• and
• (C) recovering the fermentation product from the fermentation.
