    Abstract: The invention relates to processes of producing sugars and/or fermentation products from pretreated cellulosic material comprising the steps of: preconditioning pretreated cellulosic material; hydrolyzing using a cellulolytic enzyme preparation; and fermenting sugars with a microorganism; wherein a solid-liquid separation step, resulting in a solid fraction and a liquid fraction, is carried out: after preconditioning, but before hydrolysis; or after hydrolysis, but before fermentation; wherein phenol oxidizing enzyme and hemicellulase are present or added during preconditioning; after preconditioning, but before hydrolysis; or during hydrolysis.

    Abstract: The invention relates to processes of multi-stage hydrolysis where different enzyme compositions are added in at least two stages of hydrolysis. In a first stage, a first enzyme composition of one or more cellulolytic enzymes and at least one of an oxidoreductase and an AA9 polypeptide having cellulolytic enhancing activity is added, followed by a latter stage in which a second enzyme composition comprising one or more cellulases is added. Also provided are processes for obtaining hydrolysis products and fermentation products using processes of the invention.
