Abstract

L'invention concerne un procédé pour convertir du xylose ou des substrats contenant du xylose, par exemple des hydrolysats de lignocellulose dans de l'éthanol au moyen de Saccharomyces cerevisiae. L'objectif de l'invention est d'améliorer le rendement d'éthanol et de réduire la production de sous-produits. A cet effet, l'invention comprend l'utilisation d'une souche de levure qui exprime un mutant connu de la xylose-réductase fongique, dans laquelle un motif de séquence Lys-Ser-Asn (homologue de Lys274-Ser-Asn276 dans la xylose réductase obtenue à partir de Candida tenuis) est substitué par Arg-Ser-Asp, ainsi que le type sauvage de la xylite déshydrogénase de la Galactocandida mastrotermitis par exemple. Ladite souche de levure contient éventuellement au moins une copie génique supplémentaire du gène pour la xylulose réductase.
