The present invention relates to recombinant filamentous fungal host cells producing cellulolytic enzyme compositions and methods of producing and using the compositions.

The present invention relates to the expression and optimisation of enzymes involved in the breakdown of lignocel-lulosic biomass. The present invention specifically relates to variants of the exoglucanase 1 of Trichoderma reesei, as well as to the use of said variants with improved efficiency in methods for breaking down cellulose and for producing biofuel.

The present invention relates to methods for constructing a filamentous fungal strain for production of multiple recombinant polypeptides having biological activity. The present invention also relates to methods for producing multiple recombinant polypeptides having biological activity in a filamentous fungal strain. The present invention also relates to filamentous fungal strains expressing multiple recombinant polypeptides having biological activity.

The invention relates to a process for the preparation of a sugar and/or fermentation product from lignocellulosic material.

Methods of making a paper product can comprise forming a substrate from a first furnish that comprises a plurality of pulp fibers, at least partially dewatering the substrate, treating a second furnish that comprises a plurality of surface enhanced pulp fibers (SEPF) at least by adding one or more enzymes to the second furnish, and sizing the dewatered substrate at least by depositing the treated second furnish onto at least one of opposing first and second surfaces of the dewatered substrate. The SEPF can have a length weighted average fiber length that is greater than or equal to 0.20 millimeters (mm) and an average hydrodynamic specific surface area that is greater than or equal to 10 square meters per gram (m.sup.2/g).

The present invention relates to a process for improving the nutritional quality of distillers dried grains (DGS) or distillers dried grains with solubles (DDGS) produced as a co-product of a fermentation product production process, processes for producing fermentation products, as well as enzyme blends used in the processes.

The present invention relates to the expression and optimization of enzymes involved in the breakdown of lignocellulosic biomass. Disclosed are variants of the exoglucanase 1 of Trichoderma reesei, as well as the use of said variants with improved efficiency in methods for breaking down cellulose and for producing biofuel.

A method produces xylo-oligosaccharides from a biomass containing xylan and cellulose, which method is convenient and has a high yield of xylo-oligosaccharides because of inhibition of degradation of xylo-oligosaccharides into xylose. In the method of producing xylo-oligosaccharides, a biomass containing xylan and cellulose is hydrolyzed with a cellulase composition having at least activities of xylanase, cellobiohydrolase and -glucosidase and substantially free of -xylosidase activity during hydrolysis.

The present invention relates to methods of increasing the activity of a polypeptide having cellulolytic enhancing activity, comprising: adding a soluble activating divalent metal cation to a composition comprising the polypeptide having cellulolytic enhancing activity, wherein the presence of the soluble activating divalent metal cation and the polypeptide having cellulolytic enhancing activity increases degradation or conversion of a cellulose-containing material by a cellulolytic enzyme composition compared to the polypeptide having cellulolytic enhancing activity without the soluble activating divalent metal cation. The present invention also relates to compositions, methods for degrading or converting a cellulose-containing material, and methods for producing a fermentation product.
