A fermentation medium consists of a basal medium containing a single carbohydrate (glucose, lactose, sucrose, mannitol etc.) Phenol red is added as a reagent to water-based solutions, changing color from yellow to red as the pH changes from 6.8-8.2. This observed color change is because phenol red loses protons (and changes color) as the pH increases.
