Abstract
RESUMEN Se proporciona un método para controlar la contaminación bacteriana mediante la inhibición del crecimiento bacteriano en una solución acuosa de fermentación usada en un proceso de fermentación de azúcares: El método incluye los pasos de: (a) introducir una composición de tensioactivos en la solución acuosa de fermentación; (b) introducir un ácido en la solución acuosa de fermentación en una cantidad suficiente para proporcionar un valor de pH en un intervalo de aproximadamente 4,5 o menos; y (c) mezclar la solución acuosa de fermentación con levadura, en donde la combinación de la composición de tensioactivos y el pH proporcionan efectos antibacterianos. La combinación sinérgica de la composición de tensioactivos y el pH ácido de la solución acuosa de fermentación son eficaces para controlar los niveles de una o más bacterias indeseables y/o subproductos bacterianos, mientras que la levadura (por ejemplo, Saccharomyces cerevisiae) que convierte el azúcar en etanol permanece adecuadamente viable.
