The MacConkey Broth supports the growth of most Gram-negative bacteria, while it inhibits the growth of Gram-positive bacteria due to the presence of bile salts. Bacteria that degrade lactose to acids induce a color change in the medium from violet to yellow. The change in color 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.
