General description
MacConkey Broth is a selective and differential liquid culture medium forcoliform bacteria. It is suitable for qualitative and quantitative detection ofcoliforms, particularly Escherichia coli, in various samples. Peptoneprovides nitrogen, carbon compounds, vitamins, and amino acids. The brothcontains lactose as a fermentable carbohydrate, bile salts to promote thegrowth of several species of intestinal bacteria and inhibit Gram‑positive organisms, and a pH indicator (Neutral red) that turns red inresponse to acid production from lactose fermentation. Gas production (whenDurham tubes are used) and/or color change are used as indicators of coliformactivity.
Application
