An Aspergillus mutant strain characterized in that it is an auxotrophic mutant strain of Aspergillus oryzae strain AOK27L.

Described herein is a process for producing saccharides and ethanol from biomass feedstock that includes (a) producing an enzyme composition by culturing a fungal strain(s) in the presence of a lignocellulosic medium, (b) using the enzyme composition to saccharify the biomass feedstock, and (c) fermenting the saccharified biomass feedstock to produce ethanol. The process is scalable and, in certain aspects, is capable of being deployed on farms, thereby allowing local production of saccharides and ethanol and resulting in a reduction of energy and other costs for farm operators. Optional steps to improve the biomass-to-fuel conversion efficiency are also contemplated, as are uses for byproducts of the process described herein.

The present invention relates to enzyme compositions and methods of producing and using the compositions for the saccharification of lignocellulosic material.

The present invention relates to enzyme compositions comprising a polypeptide having cellobiohydrolase II activity, a polypeptide having xylanase activity, and one or more cellulolytic proteins and their use in the degradation or conversion of cellulosic material.

The present invention relates to enzyme compositions for high temperature saccharification of cellulosic material and to uses thereof.

The present invention relates to recombinant Trichoderma host cells producing Aspergillus fumigatus cellulolytic enzyme compositions and methods of producing and using the compositions.

The purpose of the present invention is to provide a novel xylanase having various excellent enzymological properties, and that is suitable for industrial applications. The polypeptide is selected from the group consisting of (a), (b), and (c) below: (a) a polypeptide comprising an amino acid sequence selected from SEQ ID NOs: 1 to 7; (b) a polypeptide having xylanase activity and comprising an amino acid sequence selected from SEQ ID NOs: 1 to 7, the amino acid sequence having substitution, deletion, insertion, and/or addition of one or several amino acid residues; and (c) a polypeptide having xylanase activity and comprising an amino acid sequence having at least 80% identity with an amino acid sequence selected from SEQ ID NOs. 1 to 7.

The present invention relates to enzyme compositions for high temperature saccharification of cellulosic material and to uses thereof.

The present invention relates to isolated polypeptides having xylanase activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods for producing and using the polypeptides.
