Abstract

The note describes a new species of toxic cyanobacteria Microcystis wesenbergii (Komárek) Komárek ex Komárek, 2006, which was discovered after the study of the periphyton community of synthetic polymeric materials during experimental vertical exposure of 45 samples of polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP). The experimental vertical module was located in the water column of the Karantinnaya Bay of the Black Sea near Sevastopol (44°37′23.0″N, 33°29′38.5″E) from August to September 2018, when the water temperature varied from +22.4 to +26.6 °C and water salinity – from 17 to 18 ‰. Microcystis wesenbergii was found at a depth of 7.6 to 9.2 m on samples of HDPE, green PET, PP, and fragments of plastic containers for polymer samples. Microcystis wesenbergii is a polymorphic, planktonic species that occurs in small quantities in the water column of stagnant and slowly flowing eutrophic and mesotrophic freshwater reservoirs; it is toxic, sometimes forming blooms; cosmopolitan, except subpolar regions. The species was found in complex colonies consisting of subcolonies reaching a maximum length of 3700 μm; the diameter of young spherical colonies ranged from 240 to 367 μm. The diameter of M. wesenbergii cells was larger than the diagnosis [(10.19 ± 0.79) μm]; the color of the cells was predominantly light brown instead of blue-green. The discovery of toxic M. wesenbergii in the Karantinnaya Bay of the Black Sea indicates high latent diversity of cyanobacteria in this water area.
