Strains ofyeast that are genetically modified so as to co-express a gene coding a glucoamylase of fungal origin, a gene coding a glucoamylase ofvar., and a gene coding a xylanase of fungal origin. The production yield of bioethanol through these strains is greater than that of strains that are otherwise identical but that do not include the gene coding the xylanase of fungal origin. Also, a method for obtaining these yeasts, as well as the use of these yeasts in the production of bioethanol.
