The invention refers to polypeptides with polysaccharide monooxygenase activity, to a host cell that expresses them, preferably aMyceliophthora thermophilacell that recombinantly expresses at least one of these polypeptides, to an enzymatic composition comprising at least one of these polypeptides, preferably together with other cellulolytic enzymes, the use of this host cell, of at least one of the polypeptides with polysaccharide monooxygenase activity or of the enzymatic composition for the degradation of cellulosic biomass and to a process for the production of bioproducts, preferably bioethanol, including the use of this host cell, of at least one of the polypeptides of the invention or of the enzymatic composition of the invention.
