  • Processes of treating cellulosic material
    Patent number: 9809834
    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.
    Type: Grant
