Descripción

Aplicación

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.

Nota de preparación

Add 15 g to 1 litre of distilled water. Mix well, distribute into final containers and sterilize by autoclaving at 121°C for 15 minutes.
