P. aeruginosa was discovered in 1882 by Carle Gessard, a Parisian chemist and bacteriologist. It was discovered through an experiment that recognized the microbe by its water soluble pigments that turned blue-green when it was exposed to ultra violet light (Chen, 2009) P. aeruginosa is a gram-negative, rod shaped bacterium that causes disease in animals and humans. It can be found in soil, water, skin microbiota, and man-made environments. P. aeruginosa cells measure 0.5 to 1.0 µm by 3 to 4 µm, and possess a single polar flagellum. P. aeruginosa produces the pigment pyocyanin when grown on minimal medium or found in infections, giving it a greenish-blue presence (J.R. Govan & V. Deretic, 1996, Tatterson & Deretic, 2001).
