Oxoid BUFFERED PEPTONE WATER CM0509T

Oxoid Buffered Peptone Water CM0509T

Oxoid Buffered Peptone Water CM0509T is a pre-enrichment medium specifically developed to promote the recovery and growth of sub-lethally injured microorganisms, especially Salmonella species, from food and environmental samples. It complies with international standards such as ISO 6579 for the detection of Salmonella and serves as a reliable preparatory medium for subsequent selective enrichment and plating. The buffered formulation maintains a stable pH during bacterial growth, ensuring the recovery of stressed organisms during food safety testing.

Features

• ideal pre-enrichment medium – formulated for the revival of sub-lethally damaged microorganisms

• pH buffered system – maintains medium stability and supports optimal bacterial growth

• conforms to ISO 6579 – recommended by international standards for Salmonella detection

• high nutritional content – includes peptones to support the growth of a wide range of bacteria

• suitable for diverse sample types – food, environmental, and clinical samples

• ready for laboratory preparation – provided in dehydrated format for efficient reconstitution

Application

• food microbiology – used in pre-enrichment of Salmonella in raw and processed foods

• environmental monitoring – assists in detecting pathogens in environmental swabs and water
