Adsorption of cadmium and lead onto live and dead cell mass of Pseudomonas aeruginosa: A dataset

Abstract

In this research heavy metals, Cd and Pb, adsorption efficiency was evaluated in aqueous solutions using live and dead biomass of <i>Pseudomonas aeruginosa</i> bacteria. The various important parameters including; pH, temperature, Cd and Pb concentrations, contact time, live and dead cell mass were examined. First, the resistant <i>P. aeruginosa</i> to heavy metals identified and isolated from contaminated soil. Then, the Minimum Inhibitory Concentration (MIC) of Cd and Pb was determined for <i>P. aeruginosa</i>. The highest adsorption efficiency for Cd and Pb were 87% and 98.5%, under dead cell mass of 125 mg, pH 7, temperature 35 °C and contact time 90 min, respectively. The results of this study showed that <i>P. aeruginosa</i> have a high ability to adsorption of Cd and Pb in aqueous solutions.
