Endophytic fungi mediated silver nanoparticles as effective of antibacterial agents

Author : T. Thaslimmunisha, R. Bharathidasan, L. Prince

In the present study of fifteen endophytic fungi isolated from Andrographis paniculata and Carica papaya plant leaf. Among, six genera and fifteen species was identified by lactophenol cotton blue mounting techniques. To induce the biosynthesize of silver nanoparticles (AgNO3) using Aspergillus flavus, Aspergillus terreus and Penicillium janthinellum and evaluate their antibacterial potential activity. The characterization of silver nanoparticles on the fungi by FT-IR, UV-VIS spectroscopy and scanning electron microscopic (SEM) analysis were performed to study the structural morphology of the biosynthesized silver nanoparticles. Antibacterial activity was performed using agar well diffusion method against Escherichia coli, Klebsiella pneumoniae, Streptococcus pyogens, Staphylococcus aureus and Pseudomonas aeruginosa. Further, investigations in the field can lead to the improvement of the medicinal methods for the treatment of microbial infections.
