BIOCONVERSION OF SILVER SALT INTO SILVER NANOPARTICLES BY GLIOCLADIUM ROSEUM

S.H. Socrates* and S. Shankar

ABSTRACT

Present study was aimed at synthesizing the eco-friendly silver nanoparticles (AgNPs) using fungus, Gliocladium roseum. The AgNPs were synthesized after the reduction of silver nitrate solution by the fungus. Formation of AgNPs was confirmed by UV-Vis spectroscopy. AgNPs were also analyzed by scanning electron microscope (SEM). The antibacterial activity of the synthesized silver nanoparticles was tested against pathogenic bacteria such as Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus species. AgNPs were showing significant antibacterial activity. The AgNPs synthesized using the Gliocladium roseum can serve as major therapeutic agent against pathogenic bacteria.

Keywords: Silver nano, Gliocladium roseum, SEM, antimicrobial.
