“…This fi nding also indicated that Pb(II), Zn(II) and Ni(II) removed was mainly bound to the cell walls and external surfaces of the biomass. Lead biosorption was maximal at pH 5.0, a value in agreement with results obtained by Veglió et al 26 who found the maximal pH for lead by Arthrobacter sp. was 5.0.…”

The biosorption of Pb(II), Zn(II) and Ni(II) from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fi t for the biosorption of Pb(II), Zn(II) and Ni(II). The maximum adsorption uptakes (q max ) of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II), Zn(II) and Ni(II), respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II) and Ni (II), while S. maltophilia was more useful for the biosorption of Zn (II).

“…It is now well accepted that metal sorption implies physicochemical interactions between metallic ions and EPS, and that interactions could be influenced by external factors, such as pH, EPS concentration, and metal concentration [5,26]. In the present work, EPS M1 was studied to examine influence of varying experimental conditions (pH, initial concentrations, counter ion, ionic strength and heavy metal mixtures) on its metal binding performance for copper and silver.…”

Metal bioremediation was studied by biosorption of analytical grade copper Cu(II) and silver Ag(I) by an exopolysaccharide (EPS) produced by marine bacteria from French Polynesia. Colorimetric analysis showed that EPS was composed of neutral sugars, uronic acids, acetate and especially high sulfate amount (29%). Metal biosorption experiments were conducted in batch process. Results showed that the maximum sorption capacities calculated according to Langmuir model were 400 mg g−1 EPS (6.29 mmol g−1) and 256 mg g ) for Cu(II) and Ag(I), respectively. The influence of pH, biosorbent concentration, ionic strength on EPS biosorption capacities was investigated.Results showed that bacterial EPS can be considered as very promising for copper and silver bioremediation. Further development in dynamic and continuous process at the industrial scale will be organized next.
