Response of in Free and Alginate Immobilized Cells to Heavy Metals Toxicity.

Effects of 12 heavy metals on growth of free and alginate-immobilized cells of the alga were investigated. The tested metals ions include Al, As, Cd, Co, Cr, Cu, Hg, Se, Ni, Pb, Sr, and Zn. Toxicity values (EC) were calculated by graphical interpolation from dose-response curves.
