Abstract
The objective of the present study was to evaluate the feasibility of a strategy to remove lead [Pb(II)] from aqueous waste using Brevundimonas vesicularis, a bacterial species isolated from contaminated soil. Batch studies were conducted using free and immobilized biomass and the optimum conditions for removal of lead from solutions were determined. The maximum specific lead uptake of the dry biomass was found to be 12.4 mg g−1. Column study was conducted using immobilized biomass and the maximum specific lead uptake was 74.8 mg g−1. It is concluded that Brevundimonas vesicularis is a promising biosorbent to remove lead from contaminated wastewater.
