Abstract

La invencion se refiere en general a productos y procesos usados para determinar la presencia de bacterias en una muestra y particularmente se refiere a un medio de cultivo que se puede usar en productos y procesos para permitir la fácil deteccion y recuente de Entorobacteriaceae. El medio de cultivo bacteriano que facilita la fácil deteccion y recuento de bacterias es una mezcla de peptona de gelatina y extracto de levadura, lactosa o glucosa, cloruro de sodio, sales biliares, goma guar y una cantidad de exceso de tinte de sulfonftaleína suficiente para proporcionar una alta concentracion de tinte en una proximidad cercana de las bacterias en crecimiento a fin de permitir la deteccion y recuento de las bacterias en crecimiento.
