Biosynthesis of silver nanoparticles with the participation of extracellular Mn-dependent peroxidase from Azospirillum

Аннотация

The accumulation of nanoparticles of colloidal silver with spherical shape in culture liquid of Azospirillum brasilense has been shown by transmission electron microscopy. Bacterial extracellular Mn-peroxidases were found to participate in silver reduction from silver nitrate with the formation of nanoparticles. A mechanism of extracellular biosynthesis of silver nanoparticles by A. brasilense bacteria was proposed.
