Levedura recombinante molécula de ADN recombinante vetor efetivo para transformação de levedura processo para obtenção de uma levedura recombinante eficaz para fermentação de xilose a etanol processo para fermentação de glucose a etanol e levedura recombinante

摘要

Described are recombinant yeasts containing genes encoding xylose reductase, xylitol dehydrogenase and xylulokinase, and DNA molecules, vectors and methods useful for producing such yeasts. The recombinant yeasts effectively ferment xylose to ethanol, and preferred yeasts are capable of simultaneously fermenting glucose and xylose to ethanol thereby taking full advantage of these two sugar sources as they are found in agricultural biomass.
