Description 364-372
Biological synthesis of nanoparticles is emerging as a promising solution to tackle issues associated with conventional
synthesis methods. Silver nanoparticles (AgNPs), owing to their unique physiochemical and antimicrobial properties, attract
more attention. In this study, we have made an attempt to develop ecofriendly and stable AgNPs with antimicrobial
potential. AgNPs were synthesized using Gram negative Sphingobacterium multivorum supernatant and characterized by
UV-Visible spectrophotometric analysis, X-Ray Diffraction analysis, Transmission electron microscopy, Fourier transform
infrared and Dynamic Light scattering. Biosynthesized AgNPs exhibited broad spectrum antimicrobial activity against both
Gram-positive and Gram-negative bacteria. Minimum inhibitory concentration was detected 19.5 μg for E. coli and
Staphylococcus aureus. AgNPs have exhibited significant synergistic effect with all the selected antibiotics. The results
demonstrated a rapid, economic and ecofriendly method for the synthesis of stable AgNPs and further evaluation of the
antimicrobial activity against Gram-positive and Gram-negative bacteria.
