Beschreibung

Anwendung

Selektivmedium für den Nachweis und die Auszählung von Coliformen, insbesondere der Coli-aerogenes-Gruppe in Wasser, Milch und Milchprodukten.

Angaben zur Herstellung

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.
