Chromogenic Substrates

Chromogenic Substrates are soluble colourless molecules composed of a chromophore and a specific enzyme substrate. The specific enzyme can cleave the chromophore-substrate conjugate and generate an insoluble product of distinctive colour. Therefore, Chromogenic Substrates are frequently added to solid bacteriological culture media since they allow differentiation of microorganisms based on the presence of specific marker enzymes.
