This book contain different studies in bioremediation of heavy metals using different species of bacteria which isolated from soil of Basra city south of Iraq. these bacteria showed excellent bioremediation ability through two routes, bioaccumulation and biosoption which in turn emphasis using advance technique such as TEM, FTIR, and , XRD. Finally from the results we can recommended to use these bacteria in remediate heavy metals in situ after increase their biomass using bioreactor.
