Comparison of hexavalent chromium bioaccumulation in five strains of paramecium, Paramecium bursaria
The effects of hexavalent chromium on the cell growth of paramecium,Paramecium bursaria were investigated. Five strains (KBW-2, KNN-2, KNN-3, IM-6 and F1-6a) of P. bursaria (both symbiotic and algae free) were incubated in lettuce media supplemented with different concentrations of potassium dichromate under LD (12 h light: 12 h dark) conditions. To compare the bioaccumulation of chromium in...
