How does Chromogenic Culture Media technology work?
This technology is based on soluble colourless molecules (called chromogens), composed of a substrate (targeting a specific enzymatic activity) and a chromophore.
When the target organism’s enzyme cleaves the colourless chromogenic conjugate, the chromophore is released. In its unconjugated form, the chromophore exhibits its distinctive colour and, due to reduced solubility, forms a precipitate.
There are several advantages to this methodFOR THE LABORATORY TECHNICIAN: EASY TO READ AT A GLANCE
- The result is very specific and distinctive.
- clearly distinguishable with the naked eye under
normal lighting conditions. With this technique, colonies of specific
microorganisms can be recognized by their colour at a glance.

ECONOMIES OF SCALE: COST SAVINGS & FAST METHOD
- It allows for easy differentiation of microorganisms
without the complex and costly traditional detection procedures
employed in traditional agar testing techniques (No subcultures).
- By saving time and labor, it increases the efficiency of laboratory testing.
- By shortening the timeframe for identifying pathogens, it helps to prevent the spread of infections.
