1. A process for degrading or hydrolyzing a cellulosic material, comprising: contacting the cellulosic material with a cellulolytic enzyme composition and an isolated polypeptide to thereby degrade or hydrolyze the cellulosic material, wherein said isolated polypeptide has catalase activity and is selected from the group consisting of:
a) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to the sequence of amino acids 20 to 741 of SEQ ID NO: 8, and b) a fragment of the sequence of amino acids 20 to 741 of SEQ ID NO: 8, wherein the fragment has catalase activity.
