Abstract

Biomediated silver nanoparticle were synthesized using a cell free extract of a soil bacterium, Exiguobacterium mexicanum PR 10.6. The silver nanoparticles were characterised using UV-Vis spectroscopy, energy dispersive spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy. The nanoparticles ranged from 5 to 40 nm. Extracellular polymeric substance played a critical role in the reduction of silver ion and nanoparticle stabilisation when using the cell free extract. The synthesis using E. mexicanum is an effective eco-friendly, rapid method for silver nanoparticle synthesis within 1 h.
