suitability

selective for Clostridium perfringens

Application

A chromogenic Agar for enumeration detection and differentiation of Clostridium sp., in particular Clostridium perfringens, in aqueous samples. The medium is more reliable than m-CP Agar and easier to handle.

Preparation Note

Suspend 31.42 g in 400 ml distilled water and adjust the volume to 500 ml. Boil to dissolve the medium completely. Cool to 50-55°C and add 1 vial of Perfringens T.S.C. Supplement (P9352) or 1 vials of M-CP selective Supplement I (Cat. No. 51962). Dispense into petri dishes (we recommend small ones).

Other Notes

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
