Silver nanoparticles synthesized from aqueous extract of mushroom Pleurotus ostreatus exhibited inhibitory effect at the concentration of 12.5, 25, 50, and 100 mg/ml against some pathogenic bacteria and fungi such as Candida albicans, Candida guilliermondii, Candida krusei, Candida zeylanoides, Geotrichum klebahnii, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. The maximum inhibition zone was observed against C. zeylanoides at the concentration of 100 mg/ml was 24.5 mm, while the minimum inhibition zone was observed against Geotrichum at the concentration of 25 mg/ml was 8 mm and the concentration of 12.5 mg/ml was not effective against some species.
