Biosynthesis, Characterization and Antibacterial activity of Silver nanoparticles of Excoecaria agallocha L. fruit extract

Peddinti Nagababu, Vanga Umamaheswara Rao

Abstract


In this present study, Excoecaria agallocha fruit aqueous extract was used to synthesize Silver Nano Particles (Ag NPs/SNPs) which has proven as eco-friendly, nontoxic, less time consuming and energy saving. The synthesized SNPs were characterized by UV-Visible spectroscopy, FTIR and SEM studies. The SNPs were checked for the antibacterial activity against both Gram positive and Gram negative bacteria. The characterization studies clearly revealed the formation and synthesis of SNPs which also showed the inhibitory activity on the tested bacteria.  SNPs of Excoecaria agallocha fruit showed higher zone of inhibition against Micrococcus luteus, Arthrobacter protophormiae, Rhodococcus rhodochrous, Bacillus subtilis, Alcaligens faecalis, Enterobacter aerogenes, Proteus mirabilis and Salmonella enterica when compared to that of standard antibiotic, Streptomycin.
