说明

General description

Peptone Water is a culture medium used for cultivating non-fastidious organisms, studying carbohydrate fermentation patterns, and performing the indole test. The peptone in Peptone Water is rich in tryptophan, which is essential for indole production. The presence of indole can be detected using either Kovacs or Ehrlich reagent. Additionally, this medium serves as a base for carbohydrate fermentation studies by adding sugars and indicators such as bromocresol purple, phenol red, or bromothymol blue, allowing researchers to analyze fermentation capabilities effectively. Peptone Water contains peptone as a source of carbon, nitrogen, vitamins and minerals. Sodium chloride maintains the osmotic equilibrium of the medium.

Application

一种非选择性富集培养基。可用于各种碳水化合物的发酵研究。
