Abstract
In this study, the biosynthesis of gold nanoparticles by Penicillium chrysogenum, isolated from Ahar copper
mine, was investigated. The gold nanoparticles were synthesized by reducing the aqueous gold ions using the
culture supernatant of the filamentous fungi. The UV–vis spectrum displayed a characteristic peak at 532
nm that is very specific for gold nanoparticles. The XRD spectrum confirmed the presence of crystalline gold
nanoparticles. Transmission electron microscopy exhibited the intracellular formation of gold nanoparticles
in spherical, triangle and rod shapes with the size range of 5 to 100 nm.
