适用性
coliforms
应用
A selective medium for the detection and enumeration of coliform organisms, especially the Coli-aerogenes-group in water, milk and other dairy products.
制备说明
Suspend 41.5 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 need to be sterilized. No sterilization improves the recovery of the stressed microorganisms.
附注
We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
