Abstract
The present invention relates to methods for obtaining ethanol-producing yeast strains, yeast strains thus produced, and the industrial production of ethanol from said strains. More particularly, the present invention describes in its most general aspect, a method for preparing yeasts from Saccharomyces cerevisiae strains by means of the integration, into the genome of the yeast, of at least one gene encoding xylose isomerase and of at least one gene encoding xylitol dehydrogenase. The strains of the invention are useful for producing ethanol from a medium comprising at least one pentose, preferably xylose or a mixture of xylose and arabinose.
