Zusammenfassung:Described are compositions and methods relating to the expression of β-glucosidase in yeast for use in industrial ethanol production. The yeast demonstrates increased ethanol production and reduced production of unwanted side-products, including acetate. Such yeast is particularly useful for large-scale ethanol production from starch substrates. Se describen composiciones y métodos que se refieren a la expresión de ß-glucosidasa en levadura para su uso en la producción industrial de etanol. La levadura demuestra una producción aumentada de etanol y una producción reducida de productos secundarios no deseados, incluido el acetato. La levadura es particularmente útil para la producción de etanol a gran escala a partir de sustratos de almidón.
