A method for processing a lignocellulose material, comprises the following steps: (1) crushing and sieving the lignocellulose material, and collecting granules with a particle size of between 0.08 and 0.1 mm; (2) mixing the granules obtained in step (1) with water, and dispersing through a colloid mill to yield a suspension with a particle size of 40-80 &#x3bc;m; (3) homogenizing the suspension obtained in the step (2) under high pressure to have a particle size of between 10 and 40 &#x3bc;m; and (4) buffering the suspension obtained in the step (3) with a buffer solution of sodium acetate and acetic-acid, adding cellulase, &#x3b2;-glucosidase, and xylanase, and performing zymolysis for 36-72 hours.

Method for processing lignocellulose material

The present invention relates to a composite yeast for high concentration alcohol fermentation, which includes thermostable, acid protease, phytase, cellulose, &#x3b2;-glucanase, and pectinase, and is suitable for the high concentration alcohol fermentation for various raw materials. In addition to normal fermentation, the composite yeast of the present invention can degrade the raw materials, increase the nutrient ingredients in the mash, promote the growth of yeast and provide stress tolerance protection.

The present invention provides a method for extracting glucan and mannan from the cell wall of a microorganism. Specifically, the method of the present invention in one embodiment comprises the steps of: a) treating the cells of the microorganism with an alkaline protease and an mannanase; b) separating the mixture from step a) into a heavy phase and a light phase; c) drying the heavy phase obtained from step b), obtaining the glucan preparation; and d) drying the light phase obtained from step b), obtaining the mannan preparation. Optionally, in the step c), the heavy phase obtained from step b) may be treated sequentially with an alkali and an acid, and separated again into a heavy phase and a light phase. The heavy phase is dried, obtaining the glucan preparation. The present invention further relates to the glucan preparation and mannan preparation produced thereby, and the uses thereof.
