Compositions Comprising A Polypeptide Having Cellulolytic Enhancing Activity And A Dioxy Compound And Uses Thereof

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 and a dioxy compound, wherein the combination of the polypeptide having cellulolytic enhancing activity and the dioxy compound enhances hydrolysis of the cellulosic material by the enzyme composition;
• (b) fermenting the saccharified cellulosic material with one or more fermenting microorganisms to produce the fermentation product;
• and
• (c) recovering the fermentation product from the fermentation.
