Abstract
In this study, a bacterial species which could remove lead from wastewater was
isolated from lead contaminated soil prepared in the laboratory. Based on the biochemical and
morphological characterization the bacteria were identified as Brevundimonas vesicularis. The biosorption
potentiel of powdered dry biomass of B. Vesicularis was investigated by batch adsorption
experiments. It was found that, the bio-sorption capacities were significantly affected by the pH and
initial concentration of the solution, bio-sorbent dosage and contact time. Batch and isothermal
studies were carried out at optimum pH of 4. The rate of bio-sorption was found to be fast during the
initial 10min and it reached equilibrium by 60min. Langmuir isotherm model was suitable for describing
the bio-sorption of lead by B. Vesicularis. The results indicated that, the dry biomass of B. Vesicularis
is suitable as an efficient bio-sorbent for the removal of lead from wastewater.
