Descrizione

Applicazioni

A selective medium for the detection and enumeration of coliform organisms, especially the Coli-aerogenes-group in water, milk and other dairy products.

Nota sulla preparazione

Suspend 38.5 g in 1 litre of distilled water and let it sock for 5 minutes. Bring to boil and distribute into plates or tubes. Sterilization at 121°C for 15 minutes is optional, but if the medium is to be used on the same day of preparation it needs to be sterilized. But through sterilization may the medium is going to be turbid. No sterilization improves the recovery of the stressed microorganisms.
