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.

General description

The Granucult^® Listeria Enrichment Broth formulation is a modified Tryptic Soy (CASO) Broth with an additional 6 g/liter of yeast extract. The inhibition of undesired accompanying flora is achieved by the addition of acriflavin HCl, cycloheximide, and nalidixic acid. In contrary to Listeria Enrichment Broth (Base) (1.11951), this broth already contains antibiotic substances.
