Description

Other Notes

Direct plating method for enumeration of E. coli in water

Application

A liquid medium for the detection of indole-forming microorganisms due to its high content of tryptophan, it is more reliable than peptone water for this purpose.

Tryptone water is primarily used for the cultivation and maintenance of fastidious aerobic and facultative microorganisms such as Escherichia coli and Pseudomonas species.
