Application

M-17 Agar media is proposed for the cultivation, detection and enumeration of Iactic streptococci in milk and dairy products. The M-17 media are superior to other comparable culture media for the cultivation of the fastidious species Streptococcus cremoris, Streptococcus diacetilactis and Streptococcus Iactis. It is also suitable for cultivation and maintenance of starter cultures for cheese and yogurt manufacturing. This medium helps in detecting streptococcal mutants which are lactose non-fermenters. M-17 Agar media may also be used for the differentiation of bacteriophages infecting lactic streptococci.

Preparation Note

Dissolve 50 g in 950 ml distilled water and sterilize by autoclaving at 121°C for 15 minutes. After cooling add 50 ml aseptic 10% lactose solution.

Footnote

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.
