Abstract
This invention generally relates to products and processes used to determine the presence of Enterobacteriaceae in a sample and particularly relates to a bacterial culture medium which may be used in products and processes to allow early detection and enumeration of Enterobacteriaceae in a sample. The bacterial culture medium which facilitates the early detection and enumeration of Enterobacteriaceae contains a selected amount of glucose, pH indicator and buffer which prevent diffusion of colored indicator zones associated with growing bacteria in the medium.
