Zusammenfassung:The invention relates to a process for the preparation of a fermentation product from ligno-cellulosic material, comprising the following steps:a) optionally pre-treatment of the ligno-cellulosic material;b) optionally washing of the optionally pre-treated ligno-cellulosic material;c) enzymatic hydrolysis of the optionally washed and/or optionally pre-treated ligno-cellulosic material using an enzyme composition comprising at least two cellulase and whereby the enzyme composition at least comprises GH61;d) fermentation of the hydrolysed ligno-cellulosic material to produce a fermentation product; ande) optionally recovery of a fermentation product;wherein before and/or during the enzymatic hydrolysis oxygen is added to the ligno-cellulosic material.
