Biosorption of Copper (II) by the mMicroorganisms Isolated from Crude-Oil-Contaminated Soil.

The objective of this study was to isolate and screen the highly efficient copper-removing microorganisms from the petroleum hydrocarbon (PH)-contaminated sites in the Amazonian rain forest in Ecuador. Two bacterial strains (strain UEAB3 and UEAB6) have shown 100% microbial resistance on the nutrien...
