The development of reliable, eco-friendly process for the synthesis of nanoparticles is an important aspect of nanotechnology. In the present study, the extracellular synthesis of Silver nanoparticles was done by reducing aqueous Ag+ with the culture supernatant of four different bacterial strains viz. Bacillus flexus, Bacillus pseudomycoides, Cronobacte runiversalis, and Kocuria rosea. The formation of silver nanoparticles was confirmed by the change in colour from colorless to brown. The synthesized nanoparticles were characterized adopting suggested instrumentations. In case of UV-Visible spectroscopy, four strong peaks were observed at 430, 410, 420 and 420 nm respectively which confirmed the synthesis of AgNPs. | Biosynthesis and characterization of silver nanoparticles
