    Description

    Oxoid™ MacConkey Broth Purple (500g) is a selective and differential medium used for the detection and enumeration of coliforms, particularly Escherichia coli and other enteric Gram-negative bacteria, from water, food, and environmental samples. The medium contains bile salts and crystal violet, which inhibit the growth of Gram-positive bacteria, and is formulated to promote the growth of coliforms. The pH indicator (neutral red) allows for the differentiation of lactose fermenters, with acid-producing bacteria turning the medium pink to red.

    Key Features:

    • Form: Dehydrated powder
    • Weight: 500g
    • Application: Detection and enumeration of coliforms, especially E. coli and other enteric Gram-negative bacteria
    • Composition: Contains bile salts and crystal violet to inhibit Gram-positive bacteria, lactose for fermentation, and neutral red for pH indicator
    • Preparation: Suspend 11.7g of the dehydrated medium in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
    • Yield: Approximately 42.7 litres of prepared medium
    • Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
    • Compliance: Suitable for use in microbiological testing protocols for the detection of coliforms in water, food, and environmental samples
