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. |
