Biosynthesis and Characterization of Silver Nanoparticles from Aspergillus   niger and its Antibacterial Activity

The biosynthesized silver nanoparticles were characterized through UV-visible spectrophotometer, Scanning Electron microscopy, Dynamic light scattering, and Fourier Transform Infrared Spectroscopy (FTIR). [...]in the present investigation is made to produce silver nanoparticles of small size using Aspergillus niger. The carbonyl groups of amino acid residues and peptides have strong ability to bind to silver. [...]the result indicates the amines; carboxylic acid and amide groups of Aspergillus niger are involved in the fabrication of silver nanoparticles showed the similarities with 29 Antibacterial activity of synthesized AgNPs: The silver nanoparticles produced from Aspergillus niger were assayed for their antibacterial activity with chloramphenicol used as standard antibiotic against Staphylococcus aureus, Klebsiella pneumonia, Escherichia coli, and Salmonella typhi. [...]the fungus Aspergillus niger has shown potential for synthesis of Ag-NPs and its showed remarkable antibacterial activity against Staphylococcus aureus, Klebsiella pneumonia, Escherichia coli, and Salmonella typhi.
