1. A process for producing a fermentation product, comprising:
(a) saccharifying a cellulosic material with an enzyme composition comprising: (i) an Aspergillus fumigatus cellobiohydrolase I; (ii) an Aspergillus fumigatus cellobiohydrolase II; (iii) an Aspergillus fumigatus beta-glucosidase or a variant thereof; and (iv) a Penicillium sp. GH61 polypeptide having cellulolytic enhancing activity; or homologs thereof; (b) fermenting the saccharified cellulosic material with one or more fermenting microorganisms to produce the fermentation product; and (c) recovering the fermentation product from the fermentation; wherein the Aspergillus fumigatus cellobiohydrolase I or homolog thereof is selected from the group consisting of: (i) a cellobiohydrolase I comprising amino acids 27 to 532 of SEQ ID NO: 2; (ii) a cellobiohydrolase I comprising an amino acid sequence having at least 90% sequence identity to amino acids 27 to 532 of SEQ ID NO: 2; (iii) a cellobiohydrolase I encoded by a polynucleotide comprising a nucleotide sequence having at least 90% sequence identity to nucleotides 79 to 1596 of SEQ ID NO: 1; and (iv) a cellobiohydrolase I encoded by a polynucleotide that hybridizes under high stringency conditions with the full-length complement of to nucleotides 79 to 1596 of SEQ ID NO: 1, wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.; wherein the Aspergillus fumigatus cellobiohydrolase II or homolog thereof is selected from the group consisting of: (i) a cellobiohydrolase II comprising amino acids 20 to 454 of SEQ ID NO: 4; (ii) a cellobiohydrolase II comprising an amino acid sequence having at least 90% sequence identity to amino acids 20 to 454 of SEQ ID NO: 4; (iii) a cellobiohydrolase II encoded by a polynucleotide comprising a nucleotide sequence having at least 90% sequence identity to nucleotides 58 to 1700 of SEQ ID NO: 3; and (iv) a cellobiohydrolase II encoded by a polynucleotide that hybridizes under high stringency conditions with the full-length complement of nucleotides 58 to 1700 of SEQ ID NO: 3, wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.; wherein the Aspergillus fumigatus beta-glucosidase or homolog thereof is selected from the group consisting of: (i) a beta-glucosidase comprising amino acids 20 to 863 of SEQ ID NO: 6; (ii) a beta-glucosidase comprising an amino acid sequence having at least 90% sequence identity to amino acids 20 to 863 of SEQ ID NO: 6; (iii) a beta-glucosidase encoded by a polynucleotide comprising a nucleotide sequence having at least 90% sequence identity to nucleotides 58 to 2580 of SEQ ID NO: 5; and (iv) a beta-glucosidase encoded by a polynucleotide that hybridizes under high stringency conditions with the full-length complement of nucleotides 58 to 2580 of SEQ ID NO: 5, wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.; wherein the Aspergillus fumigatus beta-glucosidase variant comprises one or more substitutions selected from the group consisting of F100D, S283G, N456E, and F512Y of amino acids 20 to 863 of SEQ ID NO: 6; and wherein the Penicillium sp. GH61 polypeptide having cellulolytic enhancing activity or homolog thereof is selected from the group consisting of: (i) a GH61 polypeptide having cellulolytic enhancing activity comprising to amino acids 26 to 253 of SEQ ID NO: 8; (ii) a GH61 polypeptide having cellulolytic enhancing activity comprising an amino acid sequence having at least 90% sequence identity to amino acids 26 to 253 of SEQ ID NO: 8; (iii) a GH61 polypeptide having cellulolytic enhancing activity encoded by a polynucleotide comprising a nucleotide sequence having at least 90% sequence identity to nucleotides 76 to 832 of SEQ ID NO: 7; and (iv) a GH61 polypeptide having cellulolytic enhancing activity encoded by a polynucleotide that hybridizes under high stringency conditions with the full-length complement of nucleotides 76 to 832 of SEQ ID NO: 7, wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 micrograms/ml sheared and denatured salmon sperm DNA, and 50% formamide, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C. |
