Milk-based products are rich in both lactic acid and the protein casein. Lactose fermentation to lactic acid increases the food acidity; the acid combines with the casein, and the two coagulate and precipitate.The precipitate is then removed from the milk, and the dairy product derived from it is low in â or free of â lactose.ilk-based products are rich in both lactic acid and the protein casein.

Enteric bacteria that have the ability to ferment lactose can be detected using the carbohydrate lactose, and the pH indicator neutral red. MacConkey agar is one of the most common agar plates found in a clinical microbiology lab.sing neutral red pH indicator, the agar distinguishes those Gram-negative bacteria that can ferment the sugar lactose (Lac+) from those that cannot (Lac-). This medium is also known as an indicator medium and a low selective medium. Presence of bile salts inhibits swarming by Proteus species.
