THE USE OF MARINE MICROALGAE FOR BIOTESTING THE WATERS OF SEVASTOPOL BAYS
The possibility of using monocultures of marine diatoms and dinoflagellates isolated from the plankton of the Black Sea to assess the quality of the marine environment is shown. The studies were carried out on the diatom Phaeodactylum tricornutum and two species of dinoflagellates Prorocentrum cordatum and Gyrodinium fissum . It was revealed that in different periods the investigated coastal waters in the Sevastopol region had both a depressing and a stimulating effect on the growth of dinoflagellates and an exclusively depressing effect on the growth of diatom species. The necessity of using several species of algae in carrying out complex work on biotesting of waters of the coastal Black Sea areas is highlighted.
