Application

GranuCult^® Nutrient Broth is designed as a basic medium to support the growth of fastidious and non-fastidious microbes in test samples. It is an appropriate media for carrying out sub-culturing or to revive dormant strains.

Features and Benefits

Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment Excellent wettability, solubility, and free flowing properties Convenient, with minimal component separation and clumping, even under warm or humid conditions High batch-to- batch reproducibility Prolonged shelf life of up to five years High number of test strains exceeding all regulatory demands Granulation technology allowing many supplements to be included, with no need to add these separately

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

GranuCult^® prime Nutrient Broth is a general-purpose liquid media used for the isolation and growth of less fastidious microorganisms. It consists of peptone from meat, meat extract, yeast extract and sodium chloride. All these provide the basic nutrient requirements for the cultivation of non-fastidious microbes. The media can be enriched on the addition of supplements like blood.
