Popis: | The effect of copper (10, 25 and 50 μg/L) on the population growth, physiological state, and ultrastructure of the microalga Heterosigma akashiwo (Raphidophyceae) were studied. Copper had a greater effect on the mitochondrial membrane potential than on chlorophyll a fluorescence. The neutral lipid content was lower in the exposed cell than in control cells throughout the experiment. The morphology of organelles was not altered at any copper concentration; however, the number of vacuoles in the algal cells increased at 25 and 50 μg Cu/L. |
