Pseudomonas HiVegâ„¢ Agar (For Pyocyanin) 500G

Hiveg medium enhances the elaboration of pyocyanin, a water soluble pigment by Pseudomonas species but inhibits the formation of fluorescein pigment. The fluorescein pigment diffuses from the colonies of Pseudomonas into the agar and shows blue colouration. Some Pseudomonas strains produce small amounts of fluorescein resulting in a blue-green colouration.
