This medium is recommended for selective isolation and identification of Pseudomonas aeruginosa from clinical and non clinical specimens. Peptone provides nitrogenous compounds and other essential growth nutrients. Glycerol is a source of energy and promotes pyocyanin i.e. pigment production which is characteristic of Pseudomonas. Potassium sulphate and magnesium chloride enhance pyocyanin production. Triclosan selectively inhibits gram-positive and gram-negative bacteria.
