NOVELTY - Producing (M1) fermentation product, comprises: (a) saccharifying cellulosic material with enzyme composition comprising cellobiohydrolase (CEL6) polypeptide having cellobiohydrolase-II activity, glycoside hydrolase (GH)-10 polypeptide having xylanase activity and a cellulolytic enzyme comprising endoglucanase, cellobiohydrolase or beta -glucosidase, where CEL6 polypeptide and/or GH10 polypeptides are foreign to cellulolytic enzyme; (b) fermenting saccharified cellulosic material with at least one fermenting microorganism; and (c) recovering organic fermentation product from fermentation.    USE - The method is useful for: producing a fermentation product which is organic acid, ketone, amino acid, a gas or alcohol (all claimed) including ethanol which is useful as e.g. fuel ethanol, drinking ethanol, or industrial ethanol.    ADVANTAGE - The method utilizes enzyme composition which is cost effective to produce, and increases degradation efficiency of cellulosic material.    DETAILED DESCRIPTION - Producing (M1) a fermentation product, comprises: (a) saccharifying a cellulosic material with an enzyme composition comprising a cellobiohydrolase (CEL6) polypeptide having cellobiohydrolase II activity, a glycoside hydrolase (GH)-10 polypeptide having xylanase activity, and at least one cellulolytic enzyme comprising an endoglucanase, a cellobiohydrolase, and a beta -glucosidase, where one or both of the CEL6 polypeptide having cellobiohydrolase II activity and the GH10 polypeptide having xylanase activity are foreign to the at least one cellulolytic enzyme; (b) fermenting the saccharified cellulosic material with at least one fermenting microorganism; and (c) recovering the organic fermentation product from the fermentation. The CEL6 polypeptide having cellobiohydrolase II activity is: a polypeptide having cellobiohydrolase II activity comprising an amino acid sequence having a sequence identity of at least 90% to the mature polypeptide of SEQ ID NO: 30 (comprising a fully defined sequence of 482 amino acids as given in the specification); a polypeptide having cellobiohydrolase-II activity encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 29 (comprising a fully defined sequence of 1812 nucleotides as given in the specification) or its full-length complement, where the very high stringency conditions are defined as pre-hybridization and hybridization at 42 degrees C in 5x saline-sodium phosphate-EDTA (SSPE), 0.3% sodium dodecyl sulfate (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 saline-sodium citrate (SSC), 0.2% SDS at 70 degrees C; (c) a polypeptide having cellobiohydrolase-II activity encoded by a polynucleotide comprising a nucleotide sequence having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 29 of at least 90%; and (d) a polypeptide having cellobiohydrolase II activity comprising the mature polypeptide of SEQ ID NO: 30. The GH10 polypeptide having xylanase activity is: a polypeptide having xylanase activity comprising an amino acid sequence having a sequence identity of at least 90% to the mature polypeptide of SEQ ID NO: 70 (comprising a fully defined sequence of 406 amino acids as given in the specification); a polypeptide having xylanase activity encoded by a polynucleotide that hybridizes under very high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 69 (comprising a fully defined sequence of 1327 nucleotides as given in the specification) 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; (c) a polypeptide having xylanase activity encoded by a polynucleotide comprising a nucleotide sequence having a sequence identity of at least 90% to the mature polypeptide coding sequence of SEQ ID NO: 69; and (d) a polypeptide having xylanase activity comprising the mature polypeptide of SEQ ID NO: 70. An INDEPENDENT CLAIM is also included for fermenting (M2) a cellulosic material, comprising fermenting the cellulosic material with at least one fermenting microorganism, where the cellulosic material is saccharified with the enzyme composition comprising the CEL6 polypeptide having cellobiohydrolase-II activity, the GH10 polypeptide having xylanase activity, and the cellulolytic enzymes comprising endoglucanase, cellobiohydrolase or beta -glucosidase.
