species mediated synthesis of silver nanoparticles and their antibacterial activity against opportunistic pathogens .

Application of lactic acid bacteria for synthesis of silver (AG) nanoparticles (NPs) could be a good ecological friendly alternative to chemical and physical methods. The objective of this study was to investigate the biosynthesis of silver NPs using strains and to compare their monosaccharide composition of capsular exopolysaccharides and the antibacterial activity of synthesized nanoparticles. The washed cells of 22 strains were used for silver nanoparticle biosynthesis from silver nitrate solution.
