Pretreatment is necessary, given that pyocyanin
is a redox active compound.
colony morphology Gram-staining, positive oxidase reaction, production of pyocyanin
on Mueller-Hinton agar (Oxoid UK), citrate utilization and growth at 42degC.
The blue-green appearance of pus or of an organism culture is pertaining to the combination of pyocyanin
(blue pigment) and pyoverdin (fluorescein, yellow pigment).
Enhanced bioelectricity generation by improving pyocyanin
production and membrane permeability through sophorolipid addition in Pseudomonas aeruginosa -inoculated microbial fuel cells.
These mechanisms include competition for nutrients and place, and producing chitinase, lytic enzyme, siderophores besides many antibiotics viz, 2,4-diacetylphloroglucinol, pyoluteorin, pyrrolnitrin, pyocyanin
and oomycin A (Vanitha and Umesha, 2011).
Two simple media for the demonstration of pyocyanin
To identify the phenazine antibiotics from the selected UPMP3 strain of Pseudomonas aeruginosa and assessment of its antagonistic activity of Ganoderma boninense, three antibiotics phenazine (PHZ), phenazine-l-carboxylic acid (PCA) and pyocyanin
(PYO) were extracted from the bacterial fermented broth using benzene and chloroform and detected through High-performance liquid chromatography (HPLC).
4) Lipopolysaccharide production, pili, flagella, elastases, proteases, exotoxins, pyocyanin
, and extracellular polysaccharides comprise its virulence factors.
Although in our case the profound extension of the hemangioma was obvious, the development of a scrotal ulcer should be differentially diagnosed from trauma, herpes viral infection, intrauterine infection from varicella, infection from pyocyanin
pseudomonas, aspergillus, pyogenic granuloma, pyoderma gangrenosum, and so forth .
large irregular, non-lactose fermenting colonies on MacConkey medium and pigmented colonies on nutrient agar) gram staining, oxidase reaction, production of pyocyanin
, citrate utilization test.

Inhibition of the production of the Pseudomonas aeruginosa virulence factor pyocyanin
in wildtype cells by quorum sensing autoinducer-mimics.
