Pseudomonas Agar (For Fluorescein) is recommended for the detection of fluorescein production by Pseudomonas species. It is based on the formula described by King et al as modified in the U.S. Pharmacopeia for the detection of fluorescein production. Fluorescein is a water soluble, chloroform insoluble fluorescent pigment produced by Pseudomonas species. The medium enhances the elaboration of fluorescein by Pseudomonas and inhibits the pyocyanin formation. The fluorescein pigment diffuses from the colonies of Pseudomonas into the agar and shows yellow fluorescent colouration. Some Pseudomonas strains produce small amounts of pyocyanin resulting in a yellow-green colouration. Casein enzymic hydrolysate and proteose peptone supply essential nitrogenous nutrients, carbon, sulphur and trace elements essential for the growth of Pseudomonas. Dipotassium phosphate buffers the medium while magnesium sulphate provides necessary cations for the activation of fluorescein production. Salt concentration exceeding 2
