Thermo Fisher, R454392, MRS - Pseudomonas isolation agar

Quantity: 500 g
Unit Size: Each
The formulation of this medium was developed to enhance the production of pyocyanin which aids in the presumptive identification of Pseudomonas aeruginosa. P. aeruginosa is the only species of bacteria known to produce pyocyanin, a blue-green pigment which diffuses into the medium surrounding the growth. A low phosphorus concentration in the medium facilitates pyocyanin production.
• Selective media - Irgasan inhibits many gram-positive and gram-negative bacteria other thanPseudomonasspp.
• Enhanced pigment production aids identificationThis medium contains gelatin and meat peptones to provide nutrients necessary for bacterial growth. A low phosphorus concentration in the medium facilitates pyocyanin production. The production of pyocyanin is also enhanced by magnesium chloride and potassium sulfate incorporated in the medium and with addition of glycerol to the prepared medium.
