Characterization of pyocyanin with radical scavenging and antibiofilm properties isolated from Pseudomonas aeruginosa strain BTRY1.
A biomolecule namely pyocyanin was isolated from Pseudomonas aeruginosa (BTRY1). It was confirmed by UV-Vis spectrum with absorption maxima at 270 nm and was further characterized using Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR). Spectroscopy analyses showed the presence of relevant bonds in their respective structures. Although pyocyanin had antihemolytic, antioxidant and antibiofilm activities against food pathogens, it showed no observable cytotoxicity, and thus proposed for potential use in the preservation of food.
