Abstract

The bacterium Deinococcus radiodurans has been isolated from Basra soil. On the basis of morphological, biochemical, 16S rRNA gene sequencing and phylogeny analysis, the isolates were authentically identified as D. radiodurans. The biosorption capabilities of D. radiodurans for cadmium (Cd+2) and lead (Pb+2) were monitored at different concentrations and contact times. The characterization of heavy metals around the cells of bacterial strains was observed using the Fourier Transform Infrared (FT-IR) spectrophotometer, X-ray powder diffraction analysis (XRD) and transmission electron microscope (TEM).
