Abstract

This study has been carried out to synthesis of silver nanoparticles using green synthesis by using Streptomyces sp..that
isolating from soil and Investigation the antifungal activity of it. Results showed that silver nanoparticles were synthesized
using Streptomyces sp in the presence of silver nitrate, and the color change to brown. UV-vis spectrophotometer appears to
peak in wavelength at 420 nm, which is prescribed for silver nanoparticles. Also, microscope images by Scanning electron
microscopy (SEM), showing the size of Ag nanoparticles in range 15–50 nm. Results of antifungal activity explain the ability
of biosynthesis silver nanoparticles to inhibition the growth of fungus T.rubrum.
