Thermo Fisher, R062182, Phenylalanine Agar

Name: Phenylalanine Agar
Brand: Thermo Fisher
SKU: R062182

Quantity: 20/Pk., Unit Size: Each, Differentiate enteric gram-negative bacilli (e.g., Morganella and Providencia^1, 2) on the basis of deamination of phenylalanine using Thermo Scientific™ Remel™ Phenylalanine Agar. In 1950, Henriksen reported Proteus species were able to convert phenylalanine to phenylpyruvic acid^3. Later, Buttiaux et al. described a method for detection of phenylpyruvic acid, formed as a result of phenylalanine deamination^4. Bynae incorporated phenylalanine into an agar used

Description

Quantity: 20/Pk.
Unit Size: Each
The ability of an organism to oxidatively deaminate phenylalanine to phenylpyruvic acid is an important reaction in the differentiation of Enterobacteriaceae. This criterion is used to identify and differentiate enteric gram-negative bacilli from other members of Enterobacteriaceae which lack such an activity.
• Ready to use:Convenience of a prepared media
• Easy to interpret:A positive test is indicated by green color development within 1-5 minutes, whereas there is no color change in case of a negative test.
• Recommended by the Association of Official Analytical Chemists (AOAC)^8.The medium contains yeast extract that supplies B-complex vitamins and other nutrients to support the growth of bacteria. Sodium chloride provides essential electrolytes and maintains osmotic equilibrium. Phenylalanine acts as the substrate which undergoes oxidative deamination. This reaction is catalyzed by an amino acid oxidase enzyme and yields the alpha keto acid phenylpyruvic acid. Ferric chloride (10%) added to Phenylalanine Agar after incubation serves as a chelating agent, which combines with phenylpyruvic acid to form a green color.Not all products are available for sale in all territories.
