Peptone Water is used for cultivating nonfastidious organisms, for studying carbohydrate fermentation patterns and for performing the indole test.
SUMMARY AND EXPLANATION
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.
Peptone Water contains peptone as a source of carbon, nitrogen, vitamins and minerals. Sodium chloride maintains the osmotic balance of the medium.
