Characterization of silver nanoparticles produced by biosynthesis mediated by Fusarium oxysporum under different processing conditions

Characterization of silver nanoparticles produced by biosynthesis mediated by Fusarium oxysporum... The goal of this study was the biosynthesis of silver nanoparticles (SNPs) mediated by the fungus Fusarium oxysporum, as well as the characterization of these nanoparticles including evaluation of the particles size and stability under different processing conditions. The results showed that the biosynthesis produced silver nanoparticles having a mean size of 34 nm and zeta potential values below −30 mV at the conditions used, characterizing the nanoparticles as being stable in suspension. Ultraviolet–visible spectroscopy and flame atomic absorption spectroscopy confirmed the formation of silver nanoparticles and Fourier transform infrared spectroscopy detected the bands corresponding to the binding vibration of amide I and II bands of proteins in addition to the presence of cyclic alkanes, cyclohexane, ethers, and aromatic hydrocarbons. Finally, field emission scanning electron microscopy and transmission electron microscopy revealed the formation of spherical and well-dispersed SNPs. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bioprocess and Biosystems Engineering Springer Journals
