The article presents the results of a study of the effect of heavy metals on fluorescence activity of microalgae and cyanobacteria. Based on the results of the study determined that the collection of strains of microalgae and cyanobacteria 5 crops resistant to heavy metals, 4 cultures are more sensitive to the studied concentrations of heavy metals. Some strains under the influence of the zinc and copper was observed phenomenon of plasmolysis and deformation of the cells. Influence of heavy metals on cells of microalgae and cyanobacteria have identified a number of surveyed metals toxicity, which is as follows: Cu2 + > Zn2 + > Co2 + > Ni2+. From cultures of microalgae and cyanobacteria the following types of selected for further study, as promising strains for bioremediation of contaminated aquatic ecosystems, various heavy metals: Phormidium autumnale I-5, Anabaena variabilis RI-5, Synechococcus elongatus I-4, Chlorella vulgaris sp BB-2, Chlamydomonas reinhardtii B -4.
