Abstract

The present invention relates to methods of increasing the activity of a GH61 polypeptide having cellulolytic enhancing activity, comprising: adding a divalent copper cation to a composition comprising the GH61 polypeptide having cellulolytic enhancing activity, wherein the presence of the divalent copper cation and the GH61 polypeptide having cellulolytic enhancing activity increases degradation or conversion of a cellulosic material by an enzyme composition compared to the GH61 polypeptide having cellulolytic enhancing activity without the divalent copper cation. The present invention also relates to compositions, methods for degrading or converting a cellulosic material, and methods for producing a fermentation product.
