Peptone Water is used for cultivating nonfastidious organisms, for studying carbohydrate fermentation patterns, and for performing the indole test.

• Peptone provides a source of carbon, nitrogen, vitamins, and minerals
• Sodium chloride maintains osmotic equilibrium
• Dehydrated appearance: Cream-white to light tan, free-flowing, homogeneous

The formulation of Peptone Water makes it useful for cultivating nonfastidious organisms. This nonselective medium has been used as a basal medium for biochemical tests such as carbohydrate fermentation patterns and production of indole.
