The aim of this work was to study the pyocyanin pigment from Pseudomonas aeruginosa DN9. involves optimization process parameters for enhanced production under submerged fermentation condition. During process, maximum (92.12 µg/ml) obtained with carbon source mannitole, nitrogen peptone, inorganic salt NaCl and metal ion FeSO4. Plackett Burman design Response Surface Methodology (RSM) showed KH...
A methanol-soluble extract of the bark of Myristica cinnamomea was found to exhibit anti-quorum sensing activity, and subsequent bioassay-guided isolation led to the identification of the active compound malabaricone C (1). Compound 1 inhibited violacein production by Chromobacterium violaceum CV026 when grown in the presence of a cognate signaling molecule, N-3-oxohexanoyl-homoserine lactone. ...
The quorum-quenching compounds brominated furanone C-30 and 5-fluorouracil inhibit the pathogenicity of the Pseudomonas aeruginosa laboratory strains PA01 and PA14; however, there is no report studying the effectiveness of these compounds for clinical isolates. Therefore, the effect of both quorum quenchers on the production of pyocyanin, elastase and alkaline protease of eight clinical strains...
Pseudomonas aeruginosa is the only gram-negative bacillus capable of producing the very distinctive water-soluble pigment pyocyanin. We evaluated the reliability of this characteristic as a unique test for the identification of this organism by using Tech agar (BBL Microbiology Systems, Cockeysville, Md.) medium. A retrospective and prospective analysis was performed with a total of 835 strains...
