Hippurate test reagent
Recommended in qualitative procedures to detect organisms possessing the enzyme hippurate hydrolase , which promotes the hydrolysis of the peptide bond in hippurate, releasing glycine and benzoic acid as end products. The benzoic acid can be detected by using ferric chloride indicator. To detect the glycine and nynhydrin is possible, but any free amino acid will interfere. The tube method is a rapid test used for presumptive identification of Gardnerella vaginalis, Campylobacter jejuni, Listeria monocytogenes and β-hemolytic group B streptococci.
