Chromogenic Culture Media: Decoding the “Secret Language” of Microorganisms with Color

News 18 8 月, 2025

Principle of Chromogenic Culture Media

Chromogenic culture media enable precise microbial identification through enzyme-substrate reactions. When microorganisms grow on the medium, specific enzymes interact with chromogenic substrates—composed of a chromophore and a metabolizable component. This reaction releases a colored compound, making colonies visible in distinct colors. Compared to traditional media, chromogenic methods greatly enhance sensitivity and specificity, providing faster and more accurate microbial detection.

Key Features of HuanKai Chromogenic Culture Media
