Resumen

Este trabajo tuvo como objetivo optimizar la producción de lípidos por una cepa de levadura oleaginosa, utilizando como fuente de carbono subproductos agroindustriales obtenidos de las industrias láctea y azucarera. Se utilizaron diseños de cribado (Plackett-Burman) y de optimización (Box-Behnken) para determinar la influencia de los componentes del medio de cultivo, sobre el porcentaje de lípidos acumulados y la concentración de biomasa obtenida, así como optimizar la composición del medio de cultivo, respectivamente. La concentración de triglicéridos se determinó por el método de la sulfo-fosfo-vainillina. Las ecuaciones de regresión obtenidas durante la optimización predicen valores máximos de acumulación de lípidos de 65 % y de concentración de biomasa de 13 mg/mL, resultados comparables a los obtenidos por otros investigadores y que apuntan hacia la aplicabilidad industrial de esta cepa en sistemas tecnológicos encaminados a la producción de biodiesel.
