Description

General description

The MacConkey Broth contains bile salts that inhibit the growth of gram-positive bacteria but support the growth of most gram-negative bacteria. Bacteria degrade lactose to acids that induce a color change in the medium from violet to yellow. This is indicated by the pH indicator bromocresol purple, which shows reduced inhibition compared to neutral red.

Application

MacConkey Broth is designed for the enrichment of Enterobacteriaceae and the detection of Escherichia coli in pharmaceutical products.
