摘要：
Marine coccolithophorids, Emiliania huxleyi, Gephyrocapsa oceanica and Helladosphaera sp. were found to require selenium for their growth. The optimum concentrations were 1-10 nM for SeO2 and SeO32- and above 1 mu M for seO(4)(2-). During the depletion of selenium algal growth was strongly suppressed accompanied with the decrease in net photosynthesis.
