Chromogenic technology

热固化(法)E.coli)was invented and patented by Dr Alain Rambach in1979。The introduction of this medium triggered arevolution in microbial diagnosis driven by the introduction of awhole range of media for the detection of key clinical&food borne pathogens。

 

How does Chromogenic Culture Media technology work? 

 

The power of chromogenic technology is the combination of the detection of precise enzyme activity and localized staining precipitating in the colony,allowing an easy differentation of microorganisms thanks to the coloration of grown bacteria。

 

This technology is based on soluble colorless molecule called chromogen,composed of a substrate,targeting a specific enzymatic activity and a chromophore。

 

When the target organism’s enzyme cleaves the colorless chromogenic conjugate,the chromophore is released。Inits unconjugated form,the chromophore exhibits its distinctive colorand,due to reduced solubility,forms a precipitate。

 

The result is a very specific&distinctive color-based differentiation,which is clearly distinguishable to the naked eye under normal lighting conditions。

What are the advantages of this method?

Chromogenic technology is a powerful tool for detecting targeted microorganisms even in mixed culture conditions,allowing the user to:


-Phenotypic detection,i.e.on the basis of the pattern actually expressed by the microorganism,


-Facilitate the final identification(no subculture,fewer colonies to test),


-A faster and more efficient result。

For the laboratory technician:Easy to read at a glance!

-The result is very specific and distinctive in mixed culture,


-基于颜色的排水量,


-Naked eyes reading of the plates thanks to the unique colors。With this technique,colonies of specific microorganisms can be recognized by their colorat a glance,limiting the risk of misinterpretations。

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。
