The Thermo Scientific™ Oxoid™ Cetrimide Agar (USP, EP) (Dehydrated) is a selective medium designed for the isolation and differentiation of Pseudomonas aeruginosa from a wide range of samples. Incorporating magnesium chloride and potassium sulfate, the medium enhances pigment production while inhibiting competing organisms like Klebsiella, Proteus, and Providencia spp. This formulation conforms to USP, EP, and AOAC standards, making it a trusted choice for microbial limit testing in pharmaceutical, food, and cosmetic industries.
Key Features
- Selective Isolation:
- The presence of cetrimide, a quaternary ammonium compound, suppresses Gram-positive bacteria and certain Gram-negative organisms.
- Encourages the growth of Pseudomonas aeruginosa while strongly inhibiting non-target species.
- Enhanced Pigment Production:
- Promotes the production of pyoverdin and pyocyanin, creating the characteristic fluorescent green colonies for easy identification.
- International Standards Compliance:
- Conforms to USP, EP, and AOAC guidelines for microbial limit tests and other regulatory applications.
- Wide Applicability:
- Used for testing a range of samples, including pharmaceuticals, cosmetics, and food products, as well as environmental and clinical samples.
