Cetrimide Nalidixic Acid Agar

ReadyPlate^™ 55 Cetrimide Nalidixic acid Agar is used for the isolation and enumeration of Pseudomonas aeruginosa by membrane filtration method of water.

ReadyPlate^™ 55 agar plates are stackable specially designed plates that helps increase the safety during handling, transport, incubation and comes in a lockable format. ReadyPlate^™ 55 agar plates come with a diameter of 55 mm. Cetrimide Nalidixic acid Agar is used for the isolation and enumeration of Pseudomonas aeruginosa from food and water samples. Gelatine peptone and Casein hydrolysate provides amino acids and other complex nitrogenous substances. In the presence of Cetrimide (a selective agent which acts as a quaternary ammonium cationic detergent), bacterial cells growth other than P. aeruginosa is inhibited due to the release of nitrogen and phosphorous. Nalidixic acid present in the supplement also improves the inhibition of the accompanying microbial flora. The amount of potassium sulphate and magnesium chloride enhances the pigment production of Pseudomonas aeruginosa.
