Comparison Between Silver Nanoparticles and Silver Nitrate as Antifungal Agent

Silver nanoparticles (AgNPs) were synthesized and their maximum peak appeared around 412.5 nm. Transmission Electron Microscopy (TEM) has been used to identify the size, shape and morphology of AgNPs. AgNPs were well dispersed and predominantly spherical in shapewith diameter in the range of 2–17 nm. Twelve fungal species were used to study the effect of AgNPs as antifungal agent. Geotrichum candidum was the highest fungus affected by AgNPs followed by Aspergillus flavipes while Aspergillus glaucus became the third one. The effect of AgNPs on Emericella nidulans, Aspergillus flavus, Aspergillus alliaceus, Rhizopus sp., Aspergillus niger, Aspergillus nidulans and Penicillium sp. had lowest effect. The highest effect for AgNO3 was observed on G. candidum, and then followed by E. nidulans, Rhizopus sp., Penicillium sp., A. flavipes, A. nidulans, A. niger, A. glaucus, A. ochraceus, A. alliaceus and A. flavus which were resistant against AgNO3. The effect of AgNO3 on A. oryzae was very limited. The effect of AgNPs and AgNO3 were studied. The highest value was 272.77% in case of G. candidum, but the lowest value was 83.11% in case of Penicillium sp. AgNPs had a high effect in comparison with AgNO3 in case of A. flavus, A. glaucus, A. flavipes, A. glaucus, A. oryzae, E. nidulans and A. niger. The effects of AgNO3 were higher than AgNPs in case of A. nidulans, Rhizopus sp., A. ochraceus and Penicillium sp. These values were 98.50, 86.15, 84.90 and 83.11%, respectively.
