Peptone Water is mainly used as a substrate to study indole production. Peptone Water also serves as a base for carbohydrate fermentation studies when supplemented with sugar and indicators like bromocresol purple, phenol red or bromothymol blue. Peptone Water is recommended for studying the ability of an organism to ferment a specific carbohydrate which helps in differentiating genera and species. When the pH adjusted to 8.4, Peptone Water is suitable for the cultivation and enrichment of Vibrio species. The peptone present in the medium, provides nitrogenous and carbonaceous compounds, long chain amino acids, vitamins and other essential nutrients. Sodium chloride maintains the osmotic balance of the medium. To study the fermentation ability of carbohydrates, saccharose, rhamnose, salicin are generally added in 0.5% amount separately to the basal medium before or after sterilization.
