Abstract: The invention relates to methods of saccharifying a cellulosic material comprising subjecting the cellulosic material to a laccase and a cellulolytic enzyme composition comprising a GH61 polypeptide in the presence of dissolved oxygen at a concentration in the range of 0.5-90% of the saturation level. The invention also related to methods of producing desired fermentation products, such as ethanol, using a method including a saccharification step of the invention.

Abstract: 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.

Abstract: The invention relates to methods of saccharifying a cellulosic material comprising subjecting the cellulosic material to a cellulolytic enzyme composition and a GH61 polypeptide, and optionally a catalase in the presence of dissolved oxygen at a concentration in the range of 0.5 to 10% of the saturation level. The invention also related to methods of producing desired fermentation products, such as ethanol, using a method including a saccharification step of the invention.

Abstract: The invention relates to processes of closing an observed gap in sugar yield between pure batch hydrolysis and a multi-stage hydrolysis containing a continuous reactor. Enzyme compositions containing varied ratios of cellulolytic composition and a hemicellulolytic composition preconditioning are used in multi-stage hydrolysis processes containing a continuous reactor in order to close the gap. Such enzyme compositions are useful in multi-stage saccharification of a lignocellulosic material, fermentation processes following multi-stage saccharification of a lignocellulosic material and in improving a glucose or xylose yield in multi-stage saccharification of a lignocellulosic material.

Abstract: The invention relates to processes of multi-stage hydrolysis where different enzyme compositions are added in at least two stages of hydrolysis. In a first stage, a first enzyme composition of xylanase, a beta-xylosidase and an endoglucanase is added, followed by a latter stage in which a second enzyme composition, a cellulolytic enzyme composition, is added. Also provided are processes for obtaining hydrolysis products and fermentation products using processes of the invention.

Abstract: The apparatus includes a driving shaft with a first gear wheel, a frame able to rotate within limits about the driving shaft, a servo mechanism for controlling the angular position of the frame, a valve-lifting crankshaft with a second gear wheel supported by the frame, a rocker cam assembly, a connecting rod pivotally connected to the valve-lifting crankshaft and the rocker cam assembly, a cam follower operatively connected to a charge exchange valve, and a spring for urging the cam follower against a cam lobe. The engine rotates the driving shaft. The first gear wheel rotates the second gearwheel and the valve-lifting crankshaft. The connecting rod transmits motion from the valve-lifting crankshaft to the rocker cam assembly. Stroke, lifting duration, and phase can be controlled by the angular position of the frame.
