Beschreibung

General description

MacConkey-Agar (without salt) is a powdered, non-sterile differential medium designed for microbiological applications. It is formulated without salt and crystal violet, making it suitable for culturing a wide range of microorganisms. The medium consists of agar, bile salts, lactose, neutral red, and peptone, which provide essential nutrients and selective properties for bacterial growth.

Application

Ein Differenzierungsmedium, welches das Schwärmen der meisten Proteus Arten einschränkt. Erweist sich als nützlich zum Kultivieren von Urinproben, die möglicherweise eine große Anzahl von Proteus Arten enthalten.

Preparation Note

Suspend 47 g in 1 litre of distilled water. Bring to the boil to dissolve completely. Sterilize by autoclaving at 121°C for 15 minutes. Pour into sterile petri plates. Dry the surface of the gel before inoculation.

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.
