Description

Application

For the isolation of Salmonella, Shigella and coliform bacteria, in particular E. coli, from diverse material.
Bile salts and crystal violet extensively inhibit the Gram-positive flora. The presence of lactose and neutral red indicate lactose-positive colonies from which E. coli can be identified by fluorescence in the UV.

Preparation Note

Dissolve 50.1 g in 1 litre distilled water. Autoclave at 121°C for 15 minutes.
