A color change from purple to yellow indicates growth of a bile tolerant, lactose fermenting organism such as Escherichia coli. According to the Harmonized USP/EP/JP, MacConkey Broth is used as a selective enrichment broth, with subculture performed onto MacConkey Agar.

Hardy Diagnostics MacConkey Broth is recommended for cultivating gram-negative, lactose-fermenting bacilli from water and foods as a presumptive test for coliforms. MacConkey Broth can also be used for pre-enrichment of E. coli O157 for toxin testing.

Selectively and differentially isolate enteric gram-negative bacilli using Thermo Scientific™ Remel™ MacConkey Broth. MacConkey Broth is a modification of the original bile salt broth first described by MacConkey in 1900, which contained litmus as an indicator and sodium taurocholate to inhibit gram-positive organisms 1 .

Remel MacConkey Broth is a liquid medium recommended for use in qualitative procedures for selective and differential isolation of enteric gram-negative bacilli.

MacConkey broth is suitable for presumptive tests for Escherichia coli and coliform bacteria and for determining the E. coli or coliform titer of milk, water, and other materials.

MacConkey Broth is a differential medium recommended for the selection and recovery of the Enterobacteriaceae and related enteric gram-negative bacilli.

Identify coliforms from water and milk samples with differential Thermo Scientific™ Oxoid™ MacConkey Broth (Dehydrated).

MacConkey Broth is widely used as a differential medium for detection and enumeration of coliforms from a wide variety of food and water samples. Identification is based on colour change of the medium due to the indicator neutral red used
