Biosynthesis Of Quorum Quenching Cyanobacterial Silver Nanoparticles And Their Prospectives.

Abstract

This study aimed to isolate cyanobacterial species and develop silver nanoparticles using Cyanobacterial species. Communication is the crucial rudiment of biotic systems which is regulated by complex networks of biochemical torrents. Microorganisms too have an intricately coordinated communication system known as Quorum Sensing. Quorum sensing stimulates a large array of biological activities like biofilm formation, transfer of antibiotic resistance, virulence, bioluminescence, sporulation and symbiosis within the community. It helps microorganisms to live collectively as a macro community protecting and nourishing its individuals. Quorum sensing stimulates a large array of biological activities like biofilm formation, transfer of antibiotic resistance, virulence, bioluminescence, sporulation and symbiosis within the community. Characterization of cyanobacterial silver nanoparticles using UV Visible spectroscopy was done. Susceptibility of Pseudomonas aeruginosa to antibiotics in presence of AgNPs was determined. Cyanobacterial silver nanoparticles found to control the production of pyocyanin in Pseudomonas aeruginosa due to quorum quenching activity.
