Cetrimide Agar Base
 
Catalog Number: AS-1171
 
Cetrimide agar is a selective culture medium used to isolate and presume the identity of Pseudomonas aeruginosa. This medium helps P. aeruginosa recover by preventing the majority of contaminated microbiota from growing.
A quaternary ammonium chemical called cetrimide is added, which causes bacterial cell membranes to disrupt and has a selectively inhibiting effect. Essential nutrients, including gelatin peptone, facilitate the growth of bacteria, and sodium chloride preserves the osmotic balance. Pyocyanin, a distinctive blue pigment made by P. aeruginosa, is enhanced by the addition of magnesium chloride and potassium sulfate. The production of this pigment facilitates the organism’s presumed identification. In clinical, environmental, and industrial microbiology, cetrimide agar is frequently used to identify and count P. aeruginosa.
