This kit is used for the detection of hippurate hydrolase, an enzyme produced by a number of pathogenic organisms. Hippurate is the substrate embedded into the test strips. Hippurate hydrolase produced by bacteria will hydrolyze the embedded hippurate in the test strip. One of the resulting by-products, glycine, reacts with the chromogen producing a blue/purple color, indicating a positive test. This is a qualitative test. Tests are limited to cultures taken from samples that have been incubated for at least 24 hours.

Application
The test is based on hydrolysis of substrate (sodium hippurate) by the bacterial enzyme hippurate hydrolase and production of benzoic acid and glycine. Glycine produced by this enzymatic reaction is detected after 24 hours incubation in reaction with chromogen (ninhydrine) and the blue-purple substance is produced.
