Gracilaria is the second most productive genus of mariculture seaweeds after Laminaria in China. It is important to increase its economic value. The purpose of this study was to document the accumulation and biotransformation of selenium in Gracilaria lemaneiformis. The seaweed was cultured for 12 days in medium containing from 0 to 2000 mg L−1 selenite. At concentrations lower than 750 mg L−1, seaweed growth was promoted and the amount of chlorophyll a decreased. The organic Se content in the seaweed was over 80% in all groups and was as much as 400 μg g−1 of dry weight. Se enrichment induced a decrease in the activities of superoxide dismutase in the seaweed cells. These results suggest that G. lemaneiformis is tolerant to Se and prevents phytotoxicity by altering various metabolic processes. Furthermore, this seaweed exhibits great potential to transform inorganic Se into the organic form and therefore could be a safe candidate for the production of Se-enriched functional food.
