Abstract

In this study, the ability of DUNALIELLA salina, strain Utex-200 in bioelimination of aluminium was investigated. First the alga was grown in the culture medium and then the effects of six concentrations of 0(control), 250, 500, 1000, 2000 and 4000 mM of ALUMINUM on the growth rate and total chlorophyll content of alga were studied for duration of 27 days. The results indicated that an increase in the ALUMINUM concentration in the medium caused decrease in the growth rate and chlorophyll content. It seemed that these effects are probably due to destruction of cell membrane and suppression of essential elements uptake, such as Ca2+ and Mg2+. The treatment of algal suspension by different concentrations of ALUMINUM resulted in algal cells-Al3+ ions binding, CELL AGGLUTINATION and sedimentation, reduction of the algal cell number in supernatant of cell suspension and consequently removal of ALUMINUM. The results of adding EDT A to algal suspension for binding of ALUMINUM and prevention of cell sedimentation confirmed algal cells-Al3+ ions binding. Also, this study indicated that not only each cell of algal suspension had defmed capacity for sedimentation of ALUMINUM, but just intact cells could bind to Al3+ ions and ALUMINUM bioelimination. On the whole, the results ofthis study indicated that strong binding of algal cells- Al3+ ions resulted in reduction of growth rate and cell division, CELL AGGLUTINATION and sedimentation and ALUMINUM bioelimination.
