TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In the method (M1), steps (a) and (b) are performed simultaneously in a simultaneous saccharification and fermentation. In the method (M2): the fermenting of the cellulosic material produces a fermentation product; and the cellulosic material is pretreated before saccharification. The method (M2) further comprises recovering the fermentation product from the fermentation. Preferred Components: The cellulolytic enzymes comprise a beta -glucosidase, Trichoderma reesei cellobiohydrolase-I (CEL7A), Trichoderma reesei cellobiohydrolase-II (CEL6A) or a Trichoderma reesei endoglucanase-I (CEL7B). The cellulolytic enzyme further comprise at least one enzyme comprising Trichoderma reesei endoglucanase II (CEL5A), Trichoderma reesei endoglucanase-V (CEL45A) or a Trichoderma reesei endoglucanase-III (CEL12A). The composition further comprises a GH61 polypeptide having cellulolytic enhancing activity. At least one of the cellulolytic enzymes, the CEL6 polypeptide having cellobiohydrolase-II activity, and/or the GH10 polypeptide having xylanase activity are in the form of a fermentation broth with or without cells. The CEL6 polypeptide having cellobiohydrolase-II activity has at least 90%, preferably 99% sequence identity to the mature polypeptide of SEQ ID NO: 30. The CEL6 polypeptide having cellobiohydrolase-II activity is encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 29 or its full-length complement, where the very high stringency conditions are defined as pre-hybridization and hybridization at 42 degrees C in 5x SSPE, 0.3% SDS, 200 mu g/ml sheared and denatured salmon sperm DNA, and 50% formamide for 12-24 hours and washing three times each for 15 minutes using 2x SSC, 0.2% SDS at 70 degrees C. The CEL6 polypeptide having cellobiohydrolase-II activity: is encoded by a polynucleotide having at least 90%, preferably 99% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 29; and comprises the mature polypeptide of SEQ ID NO: 30. The GH 10 polypeptide having xylanase activity has at least 90%, preferably 99% sequence identity to the mature polypeptide of SEQ ID NO: 70. The GH10 polypeptide having xylanase activity is encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 69 or its full-length complement, where the very high stringency conditions are defined as pre-hybridization and hybridization at 42 degrees C in 5x SSPE, 0.3% SDS, 200 mu g/ml sheared and denatured salmon sperm DNA, and 50% formamide for 12-24 hours and washing three times each for 15 minutes using 2x SSC, 0.2% SDS at 70 degrees C. The GH10 polypeptide having xylanase activity: is encoded by a polynucleotide having at least 90%, preferably 99% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 69; and comprises the mature polypeptide of SEQ ID NO: 70.
