abstract：:The presence of plasmid gene cadB did not affect Cd2+ accumulation, whereas plasmid gene cadA reduced Cd2+ accumulation by whole cells but not by membrane vesicles. Membrane vesicle studies indicated that Cd2+ uptake occurred via the Mn2+ transport system which was energized by the membrane electrical potential. Mn2+ ...
