Nodulariini on Itämeren yleisin maksamyrkky ja sitä tuottaa Nodularia spumigena –sinilevä. Nodulariini on sekä akuutisti myrkyllinen että syöpävaarallinen yhdiste. Nodulariinia esiintyy Itämeressä joka kesä erittäin runsaasti, tyypillisesti luokkaa 0,1-3 grammaa kuivattua leväkiloa kohden.

Nodularia spumigena strains NSOR10 and NSGG-1 lost heterocysts when cultures were supplemented with ammonium and therefore DNA from filaments comprised solely of vegetative cells could be subjected to PCR. Cyanobakterien Nodularia spumigena bildar långa trådar med celler på rad. De tre ljusgröna cellerna är heterocyter som är specialiserade på kvävefixering. De andra cellerna är vanliga celler som fotosyntetiserar. 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.

The active substance in this species is a cyclic pentapeptide, nodularin, with similar toxicological effects as described for the hepatotoxic peptides ( Rinehart et al. 1988 ; Eriksson 1990) . Nodularia spumigena is a bloom-forming, filamentous and N 2-fixing cyanobacterium from the Nostocales order. This species occurs in many brackish waters worldwide, but most extensive blooms are reported in estuaries, lagoons and inland waters of Australia and New Zealand [ 1 , 2 , … 2021-03-26 Nodularia is a cyanobacteria genus that is usually found in warm, brackish or saline lakes and estuaries. In brackish desert lakes it can form dense blooms. Some species of Nodularia are associated with benthic environments, but the most common toxin-forming species, Nodularia spumigena, is … Nodularia spumigena.

Of the Nodularia species present in the Baltic Sea, N. spumigena is the only planktonic species that produces nodularin (Sivonen and Jones, 1999), a predominantly intracellular (IC) hepatotoxin that resembles the microcystins, a well-studied group of cyanotoxins in freshwater ecosystems (Sivonen and Jones, 1999).

937-950 ISSN: 0921-8971 Subject: Nodularia Nodularia spumigena is a filamentous diazotrophic cyanobacterium that dominates the annual late summer cyanobacterial 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. 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.
