Colonies of Pseudomonas aeruginosa on cetrimide agar medium were large, smooth with flat edges and an elevated appearance producing greenish coloration indicating the presence of pyocyanin exo-pigments.
Kim et al (25) studied the reducing effect of cinnamaldehyde on the production of pyocyanin, the swarming motility, and the hemolytic activity of P.
A variety of the colorful pigments, including pyocyanin (blue-green), pyoverdine (yellow-green and fluorescent), and pyorubin (red-brown), was produced in P.
aeruginosa has been simply detected morphologically, as the detection of the green pigment of pyocyanin, the hemolytic activity of the bacterial growth on blood agar plate and the proteolytic activity of the pathogen on the casein plate.
