This media formulation is in accordance with the harmonized method of USP/EP/BP/JP/IP and is used as a selective medium for the isolation of Pseudomonas aeruginosa from pharmaceutical products. It is also used for microbial limit testing for non-sterile products and for determining the ability of an organism to produce fluorescein and pyocyanin. Cetrimide (N-acetyl-N,N,N- trimethylammonium bromide) is incorporated in the medium to inhibit bacteria other than Pseudomonas aeruginosa. Cetrimide acts as a cationic detergent, as a quaternary ammonium compound, which causes nitrogen and phosphorus to be released from bacterial cells other than Pseudomonas aeruginosa. Magnesium chloride and potassium sulphate in the medium enhances the production of a blue-green pigment, pyocyanin which improves the detection of Pseudomonas on this medium. Presence of magnesium ions neutralize any EDTA present in the sample. Gelatin peptone provides the essential nutrients for growth of Pseudomonas, while glycerin serves as slow and continuous carbon source for the growing cell.
