Summary Cells of Chlorella fusca, were grown in liquid medium supplemented ,vith O.2% glucose and varied concentrations of vanadium both at 5 different light intensities and in the dark. \Vith increasing concentrations of vanadium the content of chlorophyll, P-700 and cytochrome f increased as well, each, however, in a different way. At the saturating concentration of 20 µg vanadium per litre the pigment content per dry weight was double as high as that of the vanadium-free control; the ratio of chlorophyll a/chlorophyll b increased from 2.1 to 2.9. The content of P-700 at saturating vanadium concentration was four times higher than that of the control when based on dry weight and double as high when based on chlorophyll content. By adding 20 µg V/1 to the nutrient medium the content of cytochrome f was enhanced by the factor of 3.4 when related to dry weight and by the factor of 1.5 when related to chlorophyll. Under high light conditions the effect of vanadium was reduced.
