NOVELTY - Preparing a sugar product from lignocellulosic material comprises enzymatically hydrolyzing the optionally washed and/or optionally pretreated lignocellulosic material using an enzyme composition comprising greater than or equal to 2 cellulases and where the enzyme composition comprises lytic polysaccharide monooxygenase (LPMO).    USE - The methods are used for preparing a sugar product and a fermentation product from lignocellulosic material (all claimed).    ADVANTAGE - The processes for enzymatic hydrolysis of lignocellulosic material and fermentation of sugars require a lower enzyme need, have faster conversion rates and/or higher conversion yields, and is low cost.    DETAILED DESCRIPTION - Preparing a sugar product from lignocellulosic material comprises (a) optionally, pretreating lignocellulosic material, (b) optionally, washing of the optionally pretreated lignocellulosic material, (c) enzymatically hydrolyzing the optionally washed and/or optionally pretreated lignocellulosic material using an enzyme composition comprising greater than or equal to 2 cellulases and where the enzyme composition comprises LPMO, and (d) optionally, recovering a glucose-containing composition, where oxygen is consumed in amounts corresponding to 20-5000 mmol molecular oxygen/kg glucan present in the lignocellulosic material, the oxygen is added after the pretreatment and before and/or during the enzymatic hydrolysis of the lignocellulosic material. An INDEPENDENT CLAIM is a process for preparing a fermentation product from lignocellulosic material by (a) optionally, pretreating the lignocellulosic material, (b) optionally, washing of the optionally pretreated lignocellulosic material, (c) enzymatically hydrolyzing the optionally washed and/or optionally pretreated lignocellulosic material using an enzyme composition comprising greater than or equal to 2 cellulases and where the enzyme composition comprises LPMO, and optionally purifying the hydrolyzed lignocellulosic material, (d) fermenting the hydrolyzed lignocellulosic material to produce a fermentation product, and (e) optionally, recovering a fermentation product, where oxygen is consumed in amounts corresponding to 20-5000 mmol molecular oxygen/kg glucan present in the lignocellulosic material, the oxygen is added after the pretreatment and before and/or during the enzymatic hydrolysis of the lignocellulosic material.
