  • First report of cyanobacterial bloom of Microcystis viridis (A. Braun) Lammermann in Slovenia = Prvi opis cvetenja cianobakterije Microcystis viridis (A. Braun) Lammermann v Sloveniji
    Eleršek, Tina, 1976-
    The presence of the cyanobacterial bloom of Microcystis viridis (A. Braun) Lemmermann is reported for the first time in Slovenia. After field sampling, and detailed microscopic observations, species ... analysis, chlorophyll content analysis, and cyanobacterial cyclic peptides were determined, the latter by high performance liquid chromatography (HPLC). Cells were found in colonies with limited amounts of more or less refractive mucilage. The average diameterof a cell was 4-7 gym. Three microcystins, two anabaenopeprins and planktopeptin BL 1125, were identified. The content of cyclic peptides in the bloom was in the range of 2.3-6.6 mg g-1 of cellular dry weight. M viridis wasdominant in the cyanobacterial bloom, other species being Micorcyslis wesenbergii, Microcystis aeruginosa, Anabaena flos-aque, Anabaena spiralis, Aulacoseira granulata, Closterium sp., Euglena sp., Pediastrum duplec, Scenedesmus quadricauda, Stauraslrum gracile, Trachelomonas volvocina, Trachelomonas hispida and Tetraedron limneticum. In keeping with previous studies the content of cyclic peptides in the cyanobacterial bloom was high enough to cause bloom lysis. This fact was also confirmed by field observation; not only bloom composition change, but after 8 days there was no visible cyanobacterial bloom on the Bored reservoir surface, although no heavyrain or wind was observed during this period. The discovery of M viridis bloom in Slovenia is very important, since toxic bloom constitutes a threat all over the World.
