| Abstract: | The effect of CdCl2 in a concentration range 0.01-10.0 g m-3 on the growth ofChlorella vulgaris under synchronous cultivation conditions was determined. The general biological activity, the growth multiplication factor, the cell size and shape and intracellular arrangement showed disturbances of synchronization that depended on Cd2+ concentration. The highest inhibition of all mentioned parameters was observed when Cd2+ was administered after the second hour of synchronous cultivation, whereas the administration after 6 or 8 h did not induce any significant effect. |
