Culture medium for rapid count of coliform bacteria

摘要

This invention generally relates to products and processes used to determine the presence of bacteria in a sample and particularly relates to a culture medium which may be used in products and processes to allow early detection and count of Enterobacteriaceae. The bacterial culture medium which facilitates the early detection and count of bacteria is a mixture of gelatin peptone and yeast extract, lactose or glucose, sodium chloride, bile salts, guar gum and an excess amount of sulfonphthalein dye sufficient to provide a high concentration of dye in close proximity of the growing bacteria in order to allow detection and count of the growing bacteria.
