Kinetics of silver reduction and nanoparticle formation in Aspergillus spent medium after addition of 1 mmol/L silver nitrate. Red bars: Concentration of silver ions (mmol/L). Blue bars: Absorption at 430 nm indicating the production of uncoagulated silver nanoparticles. The medium contained ammonium as the only nitrogen source. All reactions were carried out at room temperature. Error bars represent standard deviation from three replicates.
