Nodularia spumigena is a bloom-forming cyanobacterium which produces the hepatotoxin nodularin. The complete gene cluster encoding the enzymatic machinery required for the biosynthesis of nodularin in N. spumigena strain NSOR10 was sequenced and characterized. The 48-kb gene cluster consists of nine open reading frames (ORFs), ndaA to ndaI , which are transcribed from a bidirectional

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 ). 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 planktonic. The genus Nodularia(Nostocales) consists of filamentous heterocystous nitrogen-fixing cyanobacteria, which are found in brackish water and freshwater, as well as in terrestrial environments, worldwide (2, 7, 17, 35). Planktic Nodulariaform mass occurrences, especially in warm surface waters with a low N:P ratio (18, 21, 34).

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. Nodularia spumigena kallas även katthårsalg, då den ser ut som grönt katthår.

The toxicity of the fractions was verified by mouse bioassay. Thus the toxicity of the bloom samples was in all likelihood caused by Nodularia spumigena.

Nodularia spumigena is regularly bloom-forming in brackish water environments, e.g. the Baltic Sea (Sivonen 1990). 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. Nodularia is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae. They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans, the Peel-Harvey Estuary in Western Australia or the Baltic Sea. Nodularia cells occasionally form heavy algal blooms.

Baltic Sea water amended with 0.3µmoll−1 PO 4 every week Nodularia spumigena from the Baltic Sea, the coastal waters of southern Australia and Lake Iznik in Turkey. In addition to known structures, 9 new congeners of spumigins, 4 aeruginosins and 12 anabaenopeptins (nodulapeptins) were identified. The production of aeruginosins by N. spumigena was revealed in Nodularia spumigena potentially toxic species, forming heavy blooms and producing nodularin; occurrence - summer; filaments 8-12 µm wide, cells 3-4 times shorter than wide.
