Oxoid™ Muller-Kauffmann Tetrathionate-Novobiocin Broth (MKTTn) is a highly selective enrichment medium used for the isolation of Salmonella species from food and related samples. Developed through modifications of the original Muller formulation, MKTTn Broth includes ox bile, brilliant green, and novobiocin (40 mg/L) to enhance selectivity by inhibiting competing organisms such as Proteus spp.

The formulation conforms to ISO 6579:2002, making it suitable for laboratories performing Salmonella detection in compliance with internationally recognized standards. Presumptive Salmonella isolates should be confirmed through biochemical and serological testing according to the full ISO 6579 method.

Key Features:

• ISO-compliant formulation for food and feed testing
• Enhanced selectivity with ox bile, brilliant green, and novobiocin
• Suppresses non-target flora, including Proteus spp.
• Used after pre-enrichment in Buffered Peptone Water (ISO) for optimal Salmonella recovery
• Straw-coloured powder, easy to prepare and handle in laboratory workflows

Specifications:

• Description: Muller-Kauffmann Tetrathionate-Novobiocin Broth (MKTTn)
• Form: Powder
• Colour: Straw (dehydrated)
• Product Type: Dehydrated Culture Media
• Quantity: 500 g
• Unit Size: Each

Usage Notes:
Prepare according to ISO 6579:2002 methodology. Incubate inoculated broth under conditions specified in the standard. Follow up with appropriate selective plating and confirmatory tests.

Note: Not all products are available in all regions. Please inquire regarding local availability.
