Abstract:
The aim of this study was to synthesize and characterize Cr(III) nanoparticles using wastewater from electroplating industries and chromium-resistant Bacillus subtilis. Formation of Cr(III) nanoparticles was confirmed by UV-visible (UV-Vis) spectroscopy at 300 nm. The size of the nanoparticles varied from 4 to 50 nm and energy dispersive spectroscopy profile shows strong Cr peak approximately at 4.45 and 5.2 keV. The nanoparticles inhibited the growth of pathogenic bacteria Staphylococcus aureus and Escherichia coli. The cytotoxic effect of the synthesized Cr(III) nanoparticle was studied using HEK 293 cells, and the cell viability was found to decrease with increasing concentration of Cr(III) nanoparticles.
