Brilliance salmonella agar base

Product detailed description

Differentiation of Salmonella from the other organisms that grow on Brilliance salmonella agar is achieved through the inclusion of two chromogens that also target specific enzymes: caprylate esterase and β-glucosidase. Caprylate esterase is an enzyme present in all samonellae as well as some species of Klebsiella, Enterobacter and Proteus. Organisms possessing caprylate esterase cleave the chromogen to release an insoluble purple chromophore. As the cells grow, the chromophore builds up and produces a purple-coloured colony. Some Enterobacteriaceae, including Klebsiella and Enterobacter but not Salmonella, possess β-glucosidase2. If these organisms grow, they will form blue or dark blue colonies, even if they are esterase positive, which make them easy to differentiate from purple Salmonela colonies.
