Saprolegnia parasitica–mediated biosynthesis of silver nanoparticles and its antimicrobial activity

Abstract

Abstract In this work, the effect of silver nanoparticles synthesized by Saprolegnia parasitica was investigated against.Staphylococcus.aureus, Proteus mirabilis, E.coli, Trichophyton.rubrum and Candida albicans, The formation of the silver nanoparticles (AgNPs) was initially confirmed by the UV-Visible Spectroscopy. As well as using SEM, UVVisible analysis showed a strong peak at 428 nm, the SEM images of the biosynthesized SNPs showed spherical shape with a particle size in the 37 nm range. The results of the study showed that the concentration of 150 microliters of SNPs solution was the most concentration for inhibition when it used as an antimicrobial against (E. coli, S.aureus, P.mirabilis, (T.rubrum).
