Modified Pseudomonas Selective Agar with Cetrimide (Twin Pack)

Principle
Modified pseudomonas selective agar with cetrimide is composed of skimmed milk powder, peptone,
sodium chloride, yeast extract, cetrimide and agar. Skimmed milk is source of casein, hydrolyzed by
Pseudomonas to form yellow to green diffusible pigmented colonies. Peptone provides nitrogen and amino
acids and necessary nutrients. Yeast extract is source of carbon, nitrogen, vitamins and required growth
factors. Sodium chloride essential ions. Cetrimide acts as a quaternary ammonium, cationic detergent that
causes release of nitrogen and phosphorus from bacterial cells other than P. aeruginosa.
Use: Recommended for the detection and enumeration of Pseudomonas aeruginosa.
