Description

General description

GranuCult^® prime Count agar sugar-free ISO 13559 I IDF 153:2022, is used to determine the count of infective microorganisms in butter and other dairy products. Infective microorganisms are defined as organisms that are not directly involved in the microbiological production of a dairy product or that do not belong to its specific flora. This culture medium does not contain any fermentable carbohydrates and has little nutrient value, so these microorganisms can be cultivated selectively.

Application

GranuCult^® prime Count agar sugar free ISO 13559 I IDF 153:2022, is suitable for determining the count of infective microorganisms in butter and other dairy products.

Features and Benefits

• GranuCult^® offers superior granulated culture media.
• 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 allows many supplements to be included, with no need to add these separately
