Beschreibung
Zusammenfassung:	The invention relates to methods of saccharifying a cellulosic material comprising subjecting the cellulosic material to a catalase and a cellulolytic enzyme composition comprising a GH61 polypeptide in the presence of dissolved oxygen at a concentration of greater than 10% of the saturation level. The invention also related to methods of producing desired fermentation products, such as ethanol, using a method including a saccharification step of the invention. 本发明涉及糖化纤维素材料的方法，这些方法包括在浓度处于大于10％的饱和度的溶解氧的存在下使该纤维素材料经受过氧化氢酶和包括GH61多肽的纤维素分解酶组合物。本发明还涉及使用包括本发明的糖化步骤的方法生产所希望的发酵产物如乙醇的方法。
