General description

WL (Wallerstein Laboratory) Nutrient Medium (modified) is a modification of WL Nutrient Medium for the microbiological quality control employed in the beer-brewing industry.
WL Nutrient Medium has been modified by increasing the pH and reducing glucose concentration to facilitate the cultivation of a broad range of yeasts and bacteria from raw materials and the brewing industry environment.

Application

WL Nutrient Medium (modified) is suitable for the isolation and enumeration of yeasts and bacteria during microbiological control in the brewing industries.

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.
