Optimizing Physioculture Conditions for the Synthesis of Silver Nanoparticles from Aspergillus niger

Nida Tabassum Khan, Jameel N and Rehman SUA

The external physiochemical parameters such as fungal biomass quantity, pH, incubation temperature and silver nitrate concentration will not only affect the rate of synthesis of silver nanoparticles from Aspergillus niger but also its yield. So in order to enhance product yield optimization of external environment was done to control the above mentioned parameters. A peak at 420 nm was observed for silver nanoparticles by UV visible spectrometry and at 420 nm maximum synthesis of silver nanoparticles were obtained at optimum conditions i.e. 20 g of fungal biomass, alkaline pH of 9.0, incubation temperature of 60°C and 6 mM of AgNO₃ concentration.
