Dessa blomningar av cyanobakterier som även kan producera gift kan vara längs Skagerraks kuster och åren 1975 och 1976 blommade den blågröna algen Nodularia spumigena - även den giftig - i stora delar av Kattegatt. Nodularia spumigena is a filamentous, planktonic, photosynthetic, diazotrophic, bloom-forming cyanobacterium.It is usually found in salty or brackish waters. It is one of the dominating species during the extensive cyanobacterial blooms in the Baltic Sea, which are one of the largest in the world. Nodularins (NODs) are an important class of cyanotoxins, which are hepatotoxic cyclic pentapeptides that are produced by the cyanobacteria Nodularia spumigena (Žegura etal.,2011).

Nodularia spumigena is a filamentous diazotrophic cyanobacterium that dominates the annual late summer cyanobacteria! blooms in the Baltic Sea. But N. spumigena also is common in brackish water bodies worldwide, suggesting special adaptation allowing it to thrive at moderate salinities.

Nodularin is a potent hepatotoxin produced by the algal species Nodularia spumigena. The intensity of algal blooms has increased during the past decades in the Baltic Sea region, thus increasing the risk for intoxications in domestic and wild animals. Nodularia spumigena is a toxic cyanobacteria that blooms in the Baltic Sea every year.

Nodularia spumigena är kolonibildande mikroskopiska cyanobakterier, även kallade blågrönalger. Dessa bakterier förekommer i bräckt vatten världen över i tempererade områden, bland annat i Östersjön. Nodularia spumigena är en regelbundet återkommande art i Östersjöns planktonsamhälle under sommaren och kan ställa till stora problem i samband med algblomning. Algen producerar toxinet nodularin, vilket kan vara skadligt för både människor och djur.

Under phosphorus limiting conditions Nodularia spumigena have a high enzyme afﬁnity for dissolved organic phos-phorus (DOP) by production and release of alkaline phos-phatase. Additionally, they are able to degrade proteina- Author: Nakano, Mitsunori Source: Hydrobiologia 2018 v.809 no.1 pp. 111-120 ISSN: 0018-8158 Subject: Nodularia, etc ; aquatic organisms; drought; lotic systems 2018-09-01 · The toxic cyanobacterium Nodularia spumigena strain KAC68 was isolated from coastal waters at Askö, Sweden (58° 35´ N, 18° 14´ E) in 1996 (Janson and Granéli, 2002), and is available at the Kalmar Algae Collection (Linnaeus University, Kalmar, Sweden). One of the main bloom-forming species is the heterocystous cyanobacterium Nodularia spumigena. N. spumigena exhibits accelerated uptake of phosphate through the release of the extracellular enzyme alkaline phosphatase whose activity also serves as an indicator of the hydrolysis of dissolved organic phosphorus (DOP).

The strain was purified to axenicity, and has been cultivated in Z8 medium without nitrogen (Kotai, 1972) under continuous illumination since isolation. The ecological role of nodularin in cyanobacterium Nodularia spumigena is still largely unknown, as are the conditions that promote toxin production. We report a modulating effect of mesozooplankton grazing on cellular nodularin content in N. spumigena expressed as a decrease in cell-bound toxin concentration in the presence of copepods compared with the cyanobacterium in similar assemblages Nodularia spumigena producerar mest gift när det är lite kväve i vattnet men tillräckligt mycket fosfor, säger Malin Mohlin på Institutionen för marin ekologi vid Göteborgs universitet. Det innebär till exempel att om avloppsvatten i huvudsak renas från kväve, kan det leda till mer gift i blomningarna. Nodularin is a potent hepatotoxin produced by the algal species Nodularia spumigena.
