MacConkey Broth (USP)

A selective medium for the enrichment of Enterobacteriaceae and the detection of Escherichia coli in pharmaceutical products. The inclusion of Bromocresol Purple indicator makes the colour change caused by acid production from the fermentation of lactose easy to read with gas formation. The presence of Ox bile helps to suppress the growth of Gram positive and non-enteric bacterial species. This formulation complies with the Harmonized USP/EP/JP.
