General description

This formulation of Buffered Peptone Water has the advantages of the two classical diluents used for food samples: it has the revitalizing property of the peptone water and the pH change absorbing capacity of the phosphate buffer. The composition of this diluent is made according to the specification of ISO Standard 6579 for the detection of Salmonella in foods and other ISO Standards (6887 and 11133).

Application

Buffered Peptone Water is used as a dilution and non-selective pre-enrichment liquid medium. It is suitable for the preliminary non-selective enrichment of bacteria, particularly pathogenic Enterobacteriaceae, from food and animal feed, water, and other materials.
