| 摘要 | The invention relates to a method for producing alcohol from a pre-processed lignocellulosic biomass, in which the enzymatic hydrolysis step is carried out with cellulolytic and/or semicellulolytic enzymes generated by using at least one effluent resulting from another ethanol production method using a sugar plant as a raw material. This method can be integrated into a method for producing alcohol from so-called second-generation cellulosic or lignocellulosic materials, that comprises the following steps: 1) the chemical and/or physical pre-processing of a cellulosic or lignocellulosic substrate; 2) the enzymatic hydrolysis of the pre-processed substrate using cellulolytic and/or semicellulolytic enzymes; the alcoholic fermentation by an appropriate alcohol-producing microorganism of the hydrolysate from step 2) and the production of a fermentation wort; and the separation of the alcohol-producing microorganism used in step 3), with the separation/purification of the alcohol. | ||||||
