Abstract

Se describen composiciones y métodos que se refieren a levadura modificada que sobreexpresa fumarato reductasa. Las células de levadura tienen una tasa de fermentación aumentada en comparación con sus células parentales. Tales células de levadura son particularmente útiles para la producción a gran escala de etanol a partir de sustratos de almidón donde es deseable una tasa aumentada de producción de etanol. Reivindicación 2: El método según la reivindicación 1, en el que la alteración genética comprende la introducción en las células parentales de un ácido nucleico que puede dirigir la expresión de fumarato reductasa hasta un nivel mayor que el del crecimiento de las células parentales crecidas en condiciones equivalentes.
