Abstract :

Pseudomonas aeruginosa produces an assortment of extracellular pigments, of which phenazines comprise a significant portion. Pyocyanin is the main phenazine pigment associated with this particular organism. The aim of this study was to produce pyocyanin by isolate of P. aeruginosa, then tested the antibacterial and antifungal activity of the pyocyanin. It also aimed to investigate the possibility of using this pigment as textile colorant. In this study, L.16 isolate of Pseudomonas aeruginosa was obtained from a previous study in Saudi Arabia. The production of pyocyanin by these isolate was investigated. The amount of pyocyanin was determined spectrophotometrically. Pyocyanin was extracted by chloroform, the results provide evidence that the pyocyanin pigment produced by P. aeruginosa isolate has antimicrobial activity and can be effectively used as a dye for some textile materials.
