dc.description.abstractDichlorvos (DDVP) is a very toxic pesticide intentionally released into the environment, and its use raises public health and environmental concerns. Nevertheless, it is still widely used in Turkey. In this study, the biosorption of DDVP from aqueous solutions on dehydrated cells of Rhodopseudomonas palustris NU51 was studied as a function of pH, temperature, initial DDVP and biomass concentration. R. palustris NU51 strain belongs to the widely spread and the eco-friendly Rhodopseudomonas species. The best uptake was observed at pH 6.0 and 35 degrees C. As the concentration of biomass has increased, the DDVP uptake has increased from 18.7 to 31.17%, but the concentration of pesticide has decreased. When these results were applied to both Langmuir and Freundlich isotherms, the adsorption data provided an excellent fit to both isotherms and showed good agreement to Scatchard analysis. We could conclude that R. palustris NU51 strain is an excellent bacterium for the removal of pesticides and could be successfully used in wastewater treatments.
