Bioremediation of heavy metal contaminated water by microalgae

Abstract

Absorption properties of wild and mutant strains of Chlamydomonas reinhardtii and Chlorella sp. were studied in regard to ions of copper, zinc and cadmium. It is established that high accumulation ability is characteristic for cells resistant to cadmium of mutant strains of Chlamydomonas reinhardtii СС-124 Res-1, СС-124 Res-2 and for cells of a wild strain of Chlorella sp.3 allocated from water polluted by various organic substances. Opportunities are studied and prospects of the investigation strains in the sewage treatment, polluted by organic substances and ions of various heavy metals are shown.
