Beschreibung

Anwendung

Ein chromogenes Medium zur Differenzierung und Auszählung von Escherichia coli und Coliformen, welches die Membranfiltrationstechnik vereinfacht durch Reduktion der Filtrationsstufen von zwei auf eine. Zusätzlich entfallen weitere Bestätigungsschritte. Dieses Medium wird im Report der Umweltbehörde (UK) beschrieben: ′Methods for Examination of Waters and Associated Material - The Microbiology of Drinking Water (2002) - Part 4 - Methods for the isolation and enumeration of coliform bacteria and Escherichia coli (including E. coli O157:H7)′.

Angaben zur Herstellung

Suspend 88g in 1 litre of distilled water. Mix well and sterilize by autoclaving at 121°C for 15 minutes. Cool the medium to 50°C and pour into sterile Petri dishes.
