Abstract: 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 ?m; (3) homogenizing the suspension obtained in the step (2) under high pressure to have a particle size of between 10 and 40 ?m; and (4) buffering the suspension obtained in the step (3) with a buffer solution of sodium acetate and acetic-acid, adding cellulase, ?-glucosidase, and xylanase, and performing zymolysis for 36-72 hours.

Abstract: The present invention relates to a composite yeast for high concentration alcohol fermentation, which includes thermostable Saccharomyces cerevisiae, acid protease, phytase, cellulose, ?-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.

Abstract: The present invention relates to a composite yeast suitable for high concentration alcohol fermentation from sugar-containing raw materials, characterizing in that the composite yeast comprises any kind of dried yeast selected from Brewers yeast Saccharomyces cerevisiae Hansen of Saccharomyces cerevisiae, grape wine yeast Saccharomyces uvarum Beijerinek, and nutritious materials which are necessary for yeast growth, the nutritious materials include: the dried yeast 40-70 parts by weight, a nitrogen source 20-40 parts by weight, a phosphorous source 5-10 parts by weight, an other inorganic salt 2.5-5 parts by weight, a trace vitamin 1-2.5 parts by weight and a bacteriostatic 0.5-1.2 parts by weight. The present invention further relates to a method for preparation of the composite yeast suitable for high concentration alcohol fermentation from sugar-containing raw materials.

Abstract: A method for producing cellulosic ethanol is disclosed, which comprises the following steps: adding the medium containing the source materials of cellulose and/or hemicellulose to fermentation reaction vessel; adding cellulase to fermentation reaction vessel, and inoculating Candida lusitaniae; running simultaneous saccharification fermentation (SSFs) with the combined action of cellulose and Candida lusitaniae, and obtaining cellulosic ethanol by separation. Candida lusitaniae used in SSFs in present invention has higher ethanol tolerance and a higher ethanol production rate, it can use cellulose and hemicellulose as source materials and effectively produce cellulosic ethanol with cellulase in SSFs.
