Cetrimide broth is a pale amber nutrient liquid media used to detect Pseudomonas aeruginosa. Cetrimide (N-cetyl-N,N,N-trimethylammonium bromide) is added to inhibit bacteria other than Ps. aeruginosa. Its action as a quaternary ammonium cationic detergent causes nitrogen and phosphorous to be released from bacterial cells other than Ps. aeruginosa. Ps. aeruginosa is characterised by the production of pyocyanin (a blue green, water soluble, non-fluorescent, phenazine pigment) which is stimulated by the inclusion of magnesium chloride and potassium sulfate in the broth.
