Chromogenic cephalosporinase test
WebOne of the most common methods of detecting this enzyme is a simple chromogenic cephalosporinase test. In this test, a disk is impregnated with a cephalospoirn … WebChromogenic cephalosporinase test Substrate - cephalosporin. Principle: Organisms possessing β-lactamases when applied to the disk, exert their effect by opening the β-lactam ring of the substrate. This process results in a colored product which is conspicuous and hence allows detection.
