Nanotechnology involving synthesis and applications of nanomaterials is a rapidly growing field with significant applications in various areas. The attraction of silver nanoparticles (AgNPs) is mainly because of its application in therapeutics, bio molecular detection, catalysis and also antimicrobial agents etc. Microbial synthesis of nanoparticles is eco-friendly and has significant advantages over other processes. In the current study, synthesis of Silver nanoparticles by a bacterial strains isolated from Metal contaminated soil has made. Biosynthesis of silver nanoparticles was confirmed by metal ion reduction colour test which showed colour change from colourless to brown. Molecular identification of nanoparticles producing strains showed the presence of Bacillus flexus, Bacillus pseudomycoides , Bacillus flexus , Cronobacter universalis, and Kocuriarosea.
