   The change in the electric conductivity of sea water (samples from the Karantinnaya Bay, the Black Sea) was studied for the first time by a multi-day laboratory experiment, before and after pasteurization. The role of the biotic factor as the example of microalgae Tetraselmis viridis and Phaeodactylum tricornutum cultures and their algal viruses (strains TvV-S1 and PtV-S18 ) was shown. A decrease of electric conductivity of sea water during the viral lysis period was observed against the background of temperature increase of studied water environment in the experiment.

Key words: electric conductivity of sea water, algal viruses, microalgae.
