Abstract
|
|
|
|
A strain of Enterobacter cloacae isolated from soil showed the evidence of growth in medium containing 1, 500 ppm of Cd^(++) though its growth was inhibited at high cadmium concentrations. This strain accumulated 59% of cadmium into the cells during incubation in medium containing 0.5 ppm of cadmium and its uptake was nearly proportional to the dry weight of cells, the average being 7.8 mg cadmium per g dry cells. It was also found that 60-70% of cadmium accumulated in cells were distributed in the cell wall fraction.
