Abstract: Desulfotomaculum nigrificans, a typical sulfate reducing bacterium (SRB) was successfully grown in the presence of 12-210 mg/L of zinc. Complete bioremoval of zinc was achieved in 2 days for 12 mg/L while the bioremoval efficiency was about 70% in 40 days in the presence of 210 mg/L initial concentration of zinc, attesting to the inhibition of bacterial cell growth at higher zinc concentrations. The bioremoval mechanism was predominantly governed by bioprecipitation with biosorption contributing to a minor ext…
