BIOSYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES USING ENDOPHYTIC FUNGI ASPERGILLUS CONCIUS, PENICILLIUM JANTHINELLUM AND PHOMOSIS SP.

The present study of seventy one endophytic fungi isolated from Avicennia marina, Suaeda monica and Rhizophora mucronata plant leaf. Among 34 genera and 71 species was identified by Lactophenol cotton blue mounting techniques. To induce the biosynthesis of silver nanoparticles (AgNO₃) using Aspergillus conicus, Penicillium janthinellum and Phomosis sp. And evaluate their antimicrobial potential. The characterization of silver nano particles on these fungi by FT-IR, UV, and Fre-SEM analysis to confirm the reduction and it is believed that protein might have played an important role in the stabilization of silver nanoparticles. The synthesized AgNO₃ were found to be extracellular polydispersed spherical or hexagonal particles ranging from 6-12mm, 8-14mm 10-16mm in size. Antibacterial activity was performed using a Agar well diffusion method against Bacillus subtillus, E-coli, Enterobacter aurogens, Enterococcus, Klebseilla Pneumonia, Micrococus lutes, Salmonella typhi, Staphylococus aureus Streptococcus sp. Vibrio cholera. AgNO₃ can be mycosynthesized extracelluraly using A.Conicus, Penicillium janthinellum and Phomosis sp. As the fungal system. Which is highly advantageous over chemical synthesis not only because in can be synthesized on a large scale, but because of the case of downstream processing and its biomedical activity.
