The experiments carried out under natural and model conditions have shown that the metabolites of natural populations of waterbloom forming blue-green algae essentially influence the formation of algal and bacterial cenoses. The toxins produced by blue-green algae are characterized by a wide spectrum of antimicrobial action on saprophytic, pathogenic and potentially pathogenic microorganisms and viruses. At the same time, an excessive increase in the numbers of algae during the period of waterbloom, their die-off, and release of large amounts of organic compounds readily soluble in water are favorable for the development of microorganisms accompanying blue-green algae, including representatives of the pathogenic microflora.
