Aims: The objective was to demonstrate the size of silver particles produced by the filamentous fungus Phoma sp.3.2883 via adsorption and accumulation, and to confirm that this silver was in a reduced state. Methods and Results: Mycelium was freeze-dried and then shake-cultured in a silver nitrate solution. It was found that up to 13.4 mg of silver was produced per gram of dry mycelium via atomic absorption spectrometer (AAS) analysis. The silver particles adsorbed on the mycelium were observed and measured under transmission electron microscope and their estimated size was 71.06 +/- 3.46 nm. Further examination of the particles via X-ray photoelectron spectroscope confirmed that the adsorbed silver particle had been reduced. Conclusion: The frozen mycelium of Phoma sp3.2883 has the potential for use in silver nanoparticle production. Significance and Impact of the Study: Silver nanoparticles could be used in the oil industry as an important catalyst and in the field of human medicine as a bactericide. The fungus Phoma sp3.2883 is a potential biosorbent that could be used for the production of these silver nanoparticles, and may also be useful in waste detoxification and in silver recovery programmes.
