Abstract

 Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs)biosynthesized greenly using EXOPOLYSACCHARIDES (EPS) and CULTURE FREE SUPERNATANT (CFS) of WESIELLACONFUSA against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticleswere characterized by UV-visible spectra, Fourier Transformed Infrared Spectroscopy and Scanning ElectronMicroscopy. The formation of AuNPs and SNPs were confirmed by changes in colour: Colour change fromyellow to wine red and yellow to bluish purple, that indicate the formation of AuNPs from the EPS and CFSand colour change from colourless to brown that indicate the formation of SNPs from the EPS and CFS. Surface Plasmon Resonance (SRP) peaks were observed at 400nm. The particles were aggregate with sizeranged from 0. 5– 2. 6 μ m and 0. 08-1. 00 μ m for WCEPSAuNPs and WCCFSAuNPs and 0. 2-3. 0 μ m and 0. 2-2. 8 μ m for WCEPSSNPs and WCCFSSNPs. The AuNPs and SNPs had ANTIBACTERIAL ACTIVITY against the testedpathogens. The SNPs exhibited a broad spectrum of activity against the MDR E. coli strains tested pathogens. In conclusion EPS and CFS of Wesiella confusa were able to bio-reduced and bio-oxidized silver and gold forthe biosynthesis of SNPs and AuNPs. The SNPs had broad spectra of activity against E. coli strains comparedto the AuNPs.
