The invention provides enzymes which are useful for degradation of lignocellulosic materials, which is obtained from Trichoderma asperellum UPM1 and Aspergillus fumigatus UPM2 and wherein the steps includes: (a) growing of the Trichoderma asperellum UPM1 and Aspergillus fumigatus UPM2; (b) carrying out fermentation process using the fungi grown from step (a) with substrates which has been treated to obtain enzymes; and (c) recovering the enzymes from fermented products obtained from step (b). The enzymes recovered include cellulases, xylaneses, pectinases or a combination of these enzymes which can be further used to hydrolyze lignocellulosic materials for fermentable sugars.
