Abstract


A facile ecofriendly biological approach for the synthesis of selenium nanoparticles using the probiotic Lactobacillus acidophilus bacteria and its characterization is reported in this paper. The synthesized selenium nanoparticles were characterized using UV spectrometer, X-ray diffraction and transmission electron microscopy. The results of X-ray diffraction and transmission electron microscopic studies showed that the nanoparticles were in the uniform size range of 15-50 nm. The present study showed that no chemical changes occurred in selenium nanoparticles during the wet sterilization process and therefore, the wet sterilization method can effectively use to recover the elemental selenium from bacterial cells.
