Nodularins (NODs) are an important class of cyanotoxins, which are hepatotoxic cyclic pentapeptides that are produced by the cyanobacteria Nodularia spumigena (Žegura etal.,2011). The toxicity of NODs is due to the severe inhibition of the protein phosphatases 1 (PP-1), 2A (PP-2A), and 3 (PP-3), which leads to functional disturbance and structural disruption of the liver ( Chen etal.,2013a; Luckas etal.,2005 ).

Nodularia spumigena plays a major role in the productiv-ity of the Baltic Sea as it forms extensive blooms regularly. 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- ﬁlamentous cyanobacteria Nodularia spumigena* was observed. The Chlorophyll a concentrations were below average in the whole Skagerrak area. The Kattegat Anholt E 8th and 12th of August Similar species compositions and equally low chlorophyll concentrations were found at the two sampling occasions.

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 … Nodularia spumigena* and Dolichospermum sp. were found in moderate amounts. Small colonyforming cyanobacteria were abundant. The phytoplankton diversity was clearly higher than at the other Baltic stations with more than twice as many taxa present.

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.

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. 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. Photographer/artist Janina Kownacka 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. Description 11 Nodularia spumigena in the Baltic Sea produces a cyclic pentapeptide that is a hepatotoxin, based on intraperitoneal mouse bioassays (Sivonen et al.

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.

Note that for bacteria that are not Cyanobacteria (blue-gree algae), there are a large number of old names that have not been validated for use since the 1980 cut-off for nomenclature. The gas vesicles in Nodularia spumigena cells provide a mechanism to move up and down in the water column, which increases access to nutrients and other growth factors. Because Nodularia spumigena is capable of converting dissolved nitrogen gas ammonium, it can dominate blooms when inorganic nitrogen (ammonium, nitrate, and nitrite) is limiting to other types of algae. Denna art av cyanobakterie är vanligare såhär års i vattnet än katthårsalgen, Nodularia spumigenasom dominerar blomningarna när det är varmt i vattnet. Denna blomning och andra blomningar som dyker upp under hösten när de flesta av oss slutat bada kommer att gå förbi utan att de noteras.
