The present invention relates to compositions that can be used in hydrolyzing biomass such as compositions comprising a polypeptide having glycosyl hydrolase (GH) family 61/endoglucanase activity and/or a ß-glucosidase polypeptide, methods for hydrolyzing biomass material, and methods for using such compositions. L'invention concerne des compositions pouvant être utilisées pour hydrolyser la biomasse, telles que des compositions comprenant un polypeptide ayant une activité endoglucanase/glycosyl hydrolase (GH) de la famille GH61 et/ou un polypeptide ß-glucosidase. L'invention concerne également des procédés d'hydrolyse de biomasse, ainsi que des procédés d'utilisation de telles compositions.
