Application

Buffered Peptone Water is used in the testing of food and water samples. This product is suitable for the preliminary non selective enrichment of bacteria, particularly pathogenic Enterobacteriaceae such as Salmonella and Cronobacter, from food, animal feed, water, and other materials. The product is also suitable as a diluent for general use.

Disclaimer

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture medi. depending on your needs. The designations basi. plu. or prime are added to indicate the quality control leve. from basic quality control to standard QC plus to prime for full regulatory compliance.

General description

Buffered Peptone Water is rich in nutrients and produces high resuscitation rates for sub lethally injured bacteria and intense growth. The phosphate buffer system prevents bacterial damage caused by changes in the pH of the medium. Peptone including enzymatic digest of casein acts as a source of carbon, nitrogen, vitamins and minerals whilst sodium chloride maintains the osmotic balance.
GranuCult® is our new brand name for our existing granulated dehydrated culture media which apply to new EN ISO 11133:2014 and various other ISO standards and FDA-BAM / USDA-FSIS methods for testing of food and water samples. All these media are currently being updated to be fully compliant to the latest version of these standards and regulations with respect to composition and quality control and will be available shortly.

Cultivation of Shigella

Dehydrated culture media for cultivating Shigella come in granules that dissolve in water. Granulation of the media ensures homogenous distribution, which avoids clumping even in warm and humid conditions. 

Salmonella Contamination and Rapid Detection Methods

Salmonella pass through the entire food chain from animal feed, primary production, and into households or food-service establishments.

Cultivation of Shigella

Shigella spp. are predominantly connected to humans and are rarely isolated from other animals, with the exception of primates.
