Abstract

Present study was aimed at synthesizing the eco-friendly silver nanoparticles (AgNps) using endophytic fungi, Penicillium nodositatum isolated from the leaves of R. dumetorium .The AgNps were synthesized after the reduction of silver nitrate solution by the endophytic fungi 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 Escherichia coli, Streptococcus, Salmonella and Pseudomonas species. AgNps were showing significant antibacterial activity. The AgNps synthesized using the endophyte, P. nodositatum can serve as major therapeutic agent against pathogenic bacteria.
