One-step green synthesis of gold nanoparticles by mesophilic filamentous fungi

- Synthesis of gold nanoparticles by mesophilic filamentous fungi was investigated.
- The size and the shape of the nanoparticles depend on the experimental conditions.
- The average size of the nanoparticles ranges from ∼5 to ∼20 nm.
- The bioreductive compound in the extracellular supernatants is less than 3000 Da.
