N. 32 - Chromogenic media for colorful air microbial detection - SOP

The chromogenic media can be used for the direct identi cation of some microrganisms present in the air. An example of chromogenic media to be adopted is the “CHROMagar Orientation” of the companyCHROMagar that is succesfully used in the clinical eld, as well as food/beverage/envirnoment microbial quality control. This is a non-selective agar, similar to a TSA, but with the addition of chromogens that will allow the bacteria to grow in different colors, depending on the species.
