Lysine Decarboxylase Broth is recommended for differentiating Salmonella arizonae from the Bethesda Ballerup group of Enterobacteriaceae. The composition and performance criteria are in accordance with ISO 6579-1:2017.Fermentation of dextrose by the organisms leads to acid production, which causes a subsequent colour change of the bromocresol purple indicator to yellow. The acidic condition thus generated stimulates decarboxylase activity, which leads to decarboxylation of lysine to cadaverine. The alkaline conditions generated due to cadaverine production cause the bromocresol purple indicator (changed to yellow) to revert to purple colour. If the organisms do not produce decarboxylase enzyme, the colour of the medium remains yellow. Salmonella Arizonae, Salmonella Typhi, Klebsiella pneumoniae, Klebsiella aerogenes are known to decarboxylate lysine and show positive reaction.
