Abstract: The bio-accumulation of Spirulina with Cr, Zn, Se was studied. It was found that all of these trace elements can be bio-enriched by Spirulina, and they can be interacted each other in bio-accumulation. Besides Se(Ⅳ) showsd its stimulation to the growth of Spirulina and the accumulating of expolysaccharides (EPS) when its concentration is lower than 400mg/L, otherwise, the growth is restrained. The maximum of EPS is 18mg/L when the concentration of Se(Ⅳ) reaches 300mg/L, in comparison with 11mg/L EPS for the control group (without Se).

Key words: trace elements, Spirulina, expolysaccharides(EPS)
