The objective of the present study was to determine that the remediation capacity of Chromohalobacter sp. strains to lead and evaluate the biosorption of the metals in living and dead biomass. In this study sorptions of dead cells were found to be more effective than living cells. The functional groups on Chromohalobacter sp. for adsorption and biosorption were characterized by FT-IR. Acording to FT-IR results, N-H stretching (3400-3200 cm(-1)),-CH3 bending or -NO2 stretching (1450-1375 cm(-1) or 1550-1350 cm(-1)), C-O bending or stretching, vibrations (1200-1050 cm(-1)) and strong C-Br (750-500 cm(-1)) peaks were observed. This is the first study to reveal potential of Chroniohalobacter sp. for sorption of lead. It was concluded that the biosorption of lead by Chromohalobacter sp. can be used as a potential source for the bioremediation. This can be an interesting alternative for bioremediation processes of lead.
