Abstract

In the present study, nanoparticles were biologically synthesized using Aspergillus flavus isolated from Karankadu mangrove forest soil sample, Tamil Nadu, India. The cell filtrate of A. flavus was challenged with 10Mm of silver nitrate change of the mixture from pale yellow to brown indicate the synthesis of silver nanoparticles in the reaction mixture. The characterization of silver ion exposed to A. flavus strain and the reduction of silver nanoparticles was confirmed using UV-Visible spectrophotometer. Size of the synthesized silver nanoparticles was measured by Fourier Transformed Infrared Spectroscopy (FTIR) analysis. The result of scanning Electron Microscope and X-ray Diffraction suggest that the protein might have played an important role in the formation and stabilization of silver nanoparticles. Further, biosynthesized AgNPs using A. flavus cell filtrate exhibited good antibacterial and antifungal activity.
