Abstract
The synthesis of metal nanoparticles using greener methodology and its application in biological fields is a burgeoning field of research. We demonstrated the synthesis of silver nanoparticles using turnip leaf extract and its interaction with wood-degrading fungal pathogens such as Gloeophyllum abietinum, G. trabeum, Chaetomium globosum, and Phanerochaete sordida. TEM images revealed that the silver nanoparticles were predominantly spherical and loosely agglomerated with an average size of 16.14 nm. DLS measurement of silver nanoparticles revealed an average hydrodynamic diameter of ca. 39.5 nm with a zeta potential of -14.8 mV at pH 7.5. FTIR spectra revealed the presence of amine and aliphatic esters, which were involved in the reduction and stabilization of silver nanoparticles. The as-synthesized silver nanoparticles showed broad spectrum antifungal activity against wood-degrading fungi by inhibiting growth. Thus, the greener-synthesized silver nanoparticles can be used as an antifungal agent against wood-degrading fungal pathogens.
