The effects of deuterium (D) on Chlorella ellipsoidea C-27 were investigated. Cells grown in a medium prepared with deuterium oxide (D_2O) showed pronounced delays in cell growth and division; the length of a cell cycle in medium with 100 mol% D_2O was more than 5 times longer than that in medium prepared in H_2O. The delay caused by D_2O was not overcome by either indoleacetic acid or kinetin. The biological and ultrastractural characteristics of deuterated Chlorella (D-Chlorella) cells were examined. The responses of D-Chlorella to cell wall-digesting enzymes did not differ from those of normal (H-Chlorella) cells. D-Chlorella cells were enlarged, and cellular components, such as proteins, nucleic acids, lipids and ATP, were present in larger quantities than those in H-cells. The chloroplast of D-Chlorella was enlarged, but the levels of component photosynthetic pigments were significantly reduced. By contrast, mitochondria of D-Chlorella were smaller than those of H-cells. These changes in levels of cellular components and in the sizes of organelles seem to be unique to deuteration.
