Patent

CA 2479733

The present invention relates to a method for improved ethanol production from xylose utilising strain of Saccharomyces cerevisiae comprising genes for overexpression of xylose reductase, xylitol dehydrogenase and xylulokinase, wherein in addition to said genes, one or more specific genes of a defined group is overexpressed, and/or one or more genes of a defined group is deleted.

La présente invention concerne une méthode permettant de produire efficacement de l'éthanol à partir du xylose, faisant intervenir une souche de saccharomyces cerevisiae comprenant des gènes permettant une surexpression de la xylose réductase, de la xylitol déshydrogénase et de la xylulokinase. En plus de ces gènes, un ou plusieurs gènes spécifiques d'un groupe défini sont surexprimés et/ou un ou plusieurs gènes d'un groupe défini sont délétés.
