Oxoid™ Pseudomonas Cetrimide Agar 500g

Oxoid™ Pseudomonas Cetrimide Agar (500g) is a highly selective medium designed for the isolation and identification of Pseudomonas species, particularly Pseudomonas aeruginosa, from clinical, environmental, and food samples. The medium contains cetrimide, a surfactant that inhibits the growth of most other bacteria while allowing Pseudomonas species to grow. Pseudomonas aeruginosa produces distinctive colonies on this agar, characterised by a blue-green pigmentation due to the production of pyocyanin, a water-soluble pigment.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Isolation and identification of Pseudomonas species, particularly Pseudomonas aeruginosa, from clinical, environmental, and food samples
• Composition: Contains cetrimide to inhibit the growth of non-Pseudomonas bacteria, and other nutrients that support the growth of Pseudomonas species, allowing for characteristic colony formation and pigmentation
• Preparation: Suspend 38g of the dehydrated medium in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 13.2 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Suitable for use in microbiological testing protocols for the selective isolation of Pseudomonas spp.
