Abstract
The accumulation of cadmium by living and dead cells of the green microalgae Tetraselmis chuii was studied both in cell suspensions and in growing conditions. Microalgal cell suspensions accumulated a maximum of 292.60 (23.09) and 210.54 (16.05) mg Cd (g biomass)-1 when living and dried cells were used, respectively. After biosorption, the total cadmium accumulated was efficiently desorbed with concentrated EDTA solution, indicating that cadmium accumulation took place through surface structural components. During cell growth in cadmium-contaminated medium, the toxic effect of the metal proved to be higher for increasing metal concentrations in the medium. This increasing toxicity had a marked influence upon cell productivity. Cadmium was not incorporated during growth of T. chuii cells.
