Application

MacConkey Broth Purple is a differential medium used for the detection of coliforms in water samples and milk examination by MPN technique. It is a modification of the classic medium, where neutral red is replaced by a less aggressive indicator, according European Pharmacopoeia. It is also recommended by ISO Committee under the specification ISO 9308-2:1990.

Preparation Note

Suspend 40 g in 1000 ml distilled water. Dispense in test tubes with inverted Durham tubes. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.
