• The rate of excretion of glycolate by the unicellular green alga Ankistrodesmus braunii changes during its life cycle. It is high in the main growth phase during the light period with a maximum 6 hr after the start of illumination, and low during the period of cell division in the dark. The glycolate excretion is stimulated by DSPD and HPMS, while the total ^<14>CO_2-fixation is inhibited by DSPD and enhanced by HPMS. Changes in the effects of DSPD and HPMS on glycolate excretion as well as on photosynthetic ^<14>CO_2-fixation during the course of the algal life cycle were followed using the technique of synchronous culture. How far the change of glycolate excretion is due to a change of glycolate oxidase activity during the life cycle and to a change of C_2-supply from the carbon reduction cycle is discussed. The effect of DSPD on glycolate excretion suggests a participation of ferredoxin in the glycolate pathway.
