Abstract
The uptake of cadmium and responses to this metal were studied in growing Rhodotorula sp. Y11. In presence of cadmium, Y11 showed a similar lag phase with decreased μmax in comparison to the control cultures in the absence of cadmium. Different changes in contents of cell elemental composition (carotenoids, total protein, total soluble sugar, and phosphate content) were observed under cadmium pressure. Growing Rhodotorula sp. Y11 took up cadmium in a biphasic mode, involving an initial energy-independent biosorption to the cell surface, followed by a slower energy-dependent intracellular accumulation. In the presence of metabolic inhibitors, intracellular cadmium uptake of growing Y11 was significantly influenced.
