Green synthesis of silver nanoparticles using psychrotolerant strains of Tulasnella albida from South Orkney Islands (Antarctica)
Nanoparticles are widely studied due to their possible uses in biological and technological systems. Four psychrotolerant strains of Tulasnella albida isolated from Antarctica were tested and compared in their ability to synthesize silver nanoparticles. The four strains were capable of synthesizing...

Nanoparticles are widely studied due to their possible uses in biological and technological systems.
