摘要
The present invention describes a process for the production of alcohol, known as second generation production, from a lignocellulosic substrate, in which a controlled quantity of furfural is produced in situ and which comprises at least the following steps: a first step for alkaline chemical pre-treatment of the substrate; a step for adjusting the pH of the substrate; then a step for enzymatic hydrolysis of said pre-treated substrate; a step for alcoholic fermentation of the hydrolysate obtained with an alcohol-producing microorganism; a step for separation/purification; and a step for acid conversion of at least one liquid fraction into furfural, said liquid fraction being obtained during one of the preceding steps; a step for mixing said furfural obtained with the pre-treated substrate during the pH adjusting step.
