A medium recommended by the Harmonised European Pharmacopoeia for the isolation and identification of Pseudomonas aeruginosa, in non-sterile pharmaceutical samples.
Conforms to USP/EP/JP performance specification. Gelatin is a source of nitrogen whilst glycerol acts as a carbon source. Cetrimide is a quarternary ammonium compound that inhibits the growth of a wide range of Gram-positive and some Gram-negative micro-organisms. Magnesium chloride and dipotassium sulphate improve the production of pyoverdin and pyocyanin pigments that combine to give Pseudomonas aeruginosa characteristic green colonies. According to the Harmonised European Pharmacopoeia, subculture is carried out onto the medium after enrichment in Casein Soya Bean Digest Broth.
