MacCONKEY BROTH W/ NEUTRAL RED (DOUBLE STRENGTH) (VEG.)

MacConkey HiVeg Broth (Double strength) w/ Neutral Red is a modification of MacConkey Broth (Double strength) w/ Neutral Red. It is prepared by replacing animal based peptones with veg peptones and it is free from BSE/TSE risk. MacConkey Broth is widely used as a differential medium for detection and enumeration of coliforms from a wide variety of clinical, food and water samples. Identification is based on colour change of the medium due to the presence of the indicator neutral red.
MacConkey Veg Broth (Double Strength) w/ Neutral Red is recommended for the primary isolation of coliforms form large samples such as water and wastewater. The medium turns pink in case of lactose fermentors and yellow in case of lactose- non- fermenters, due to neutral red. The medium has same composition in double strength to that of MacConkey Broth, which contains neutral red as an indicator and is considered as a standard medium for the primary isolation as well as presumptive identification of coliform-aerogenes group of organisms in food and water.
