Zusammenfassung:Methods for producing acetaldehyde from ethanol are provided. In embodiments, such a method comprises (a) exposing ethanol and furfural to a biocatalyst comprising yeast alcohol dehydrogenase 1, yeast alcohol dehydrogenase 2, and yeast alcohol dehydrogenase 3, and a biocatalyst cofactor under conditions that oxidize the ethanol to acetaldehyde and reduce the furfural to furfuryl alcohol to provide a product mixture comprising the acetaldehyde and the furfuryl alcohol; and (b) recovering the acetaldehyde from the product mixture as it is being produced in step (a).
