Notes:
Abstract Cyanidium caldarium, an acidophilic, thermophilic red alga, specifically tolerates Al. The tolerance increases at lower culture temperatures. The intracellular Al concentration is kept at low levels, especially when the cells are cultured at lower temperatures. Lower Al incorporation accounts for the Al tolerance in this alga. Fe incorporation antagonizes the Al incorporation, implying that Fe transporters incorporate Al ions. Treatment with an uncoupler, carbonylcyanide m-chlorophenylhydrazone, increases the intracellular concentration of Al. These results support the hypothesis that Al ions taken up by the algal cells are exported by an energy-dependent mechanism.
