Product Description
ONPG tests can be used to differentiate slow lactose fermenters, which are thought to be deficient in permease, and non-fermenters. It is also useful to differentiate Pseudomonas cepacia and Pseudomonas maltophilia, which are positive, from other pseudomonads, which are negative. The demonstration of beta-galactosidase is accomplished by the hydrolization of ortho-nitrophenol-beta-D-galactopyranoside liberating ortho-nitrophenol with its characteristic yellow color.
