What parameters in mac conkey agar show lactose fermentation?
In MacConkey agar, lactose fermentation is indicated by the color change of the colonies. The medium contains lactose as a fermentable carbohydrate and a pH indicator, typically neutral red. When lactose is fermented by certain bacteria, it produces acid, lowering the pH and resulting in a color change to pink or red. Non-fermenters will remain colorless or pale, allowing differentiation between lactose fermenters and non-fermenters.
