Do toxic cyanobacteria blooms pose a threat to the Baltic ecosystem?

Abstract: Cyanobacteria, otherwise known as blue-green algae, are oxygenic, photosynthetic prokaryotes. They occur naturally in many fresh, marine and brackish waters worldwide and play an important role in global carbon and nitrogen cycles. In their long history, cyanobacteria have developed structures and mechanisms that enable them to survive and proliferate under different environmental conditions. In the Baltic Sea, the mass development of cyanobacteria is compounded by a high level of eutrophication. The dominant … Show more

“…Nodularia spumigena has been identified as one of the most important species causing harmful cyanobacterial blooms in the Baltic Sea (Sivonen et al, 1989;Mazur-Marzec and Pli nski, 2009). Even though several studies recognize the importance of phages in bacterial community dynamics, the only report on Nodularia-specific phages isolated from the Baltic Sea dates a decade back, when Jenkins and Hayes (2006) isolated 17 myo-and siphophages infecting N. spumigena.…”

“…and Nodularia spumigena. N. spumigena is a well-known toxin producer that affects aquatic and terrestrial organisms, and may pose a health hazard for humans (Sellner 1997;Mazur-Marzec & Pliń ski 2009). Aphanizomenon sp.…”

“…This could be partially due to the notion that cyanotoxins are relatively recalcitrant to chemical degradation [5] and were thought as nonlabile for biodegradation as well. However, advances in molecular microbial ecology have elucidated that strains of the bacterial genera Sphingomonas, Sphingosinicella, Arthrobacter, Brevibacterium, Rhodococcus, and Burkholderia can degrade microcystins (MC) and nodularins in time scales from hours to days [6, 7]. Moreover, we are now aware of eukaryotic mechanisms of cyanotoxin elimination in animal tissues [810].…”
