METHODS OF SACCHARIFYING AND FERMENTING A CELLULOSIC MATERIAL

METHODS OF SACCHARIFYING AND FERMENTING A CELLULOSIC MATERIAL

The invention relates to methods of saccharifying a cellulosic material comprising subjecting the cellulosic material to a cellulolytic enzyme composition and a GH61 polypeptide, and optionally a catalase in the presence of dissolved oxygen at a concentration in the range of 0.5 to 10% of the satura...

Zusammenfassung:The invention relates to methods of saccharifying a cellulosic material comprising subjecting the cellulosic material to a cellulolytic enzyme composition and a GH61 polypeptide, and optionally a catalase in the presence of dissolved oxygen at a concentration in the range of 0.5 to 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.
