Nodularia spumigena have aerotopes (groups of gas vesicles); they are one of four planktonic species that do. Species in this group may form dense blooms in the ocean or river estuaries, brackish coastal lakes and lagoons, and high-salinity inland lakes and reservoirs. Abstract. The object of this work was to determine, using a full-factorial experiment, the influence of temperature, irradiance and salinity on growth and hepatotoxin production by Nodularia spumigena, isolated from Lake Alexandrina in the south-east of South Australia. Nodularia ist eine Gattung filamentöser Cyanobakterien.Im Sommer kommt es in der Ostsee regelmäßig zu Oberflächenblüten der toxischen Art Nodularia spumigena, die auch die Typusart ist. Nodularia on sinivetikate perekond, kuhu kuulub ligemale 21 liiki vetikaid. Nodularia liike võib leiduda nii mullastikus, avavees, bentoses kui ka perifüütonina.Perekonna tüüpliigiks peetakse riimveelistes veekogudes ulatuslikke toksilisi õitsenguid põhjustavat Nodularia spumigena't.

När cellerna dör läcker allt cellinnehåll ut i vattnet, inklusive giftet. – Giftet som N. spumigena tillverkar påverkar levern, så man måste dricka vattnet för att få i sig giftet, förklarar Maria Karlberg. De heter knippblomsalg, Aphanizomenon, Den är vanligare än katthårsalgen, Nodularia spumigena som blommar med senare på sommaren när det är varmt i vattnet. Genom att dra en planktonhåv genom vattnet samlas och koncentreras små växtplankton och cyanobakterier. Abstract. Blooms of the cyanobacterium Nodularia spumigena occur regularly in the Baltic Sea typically producing a wide range of bioactive peptides including the hepatotoxin nodularin (NOD), spumigins, anabaenopeptins and nodulopeptins (molecular weights: 917, 901 and 899 Da).

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 is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae.

This species is also able to perform akinete differentiation, thus favoring the success of their populations under adverse conditions. In southern Brazil, N. spumigena has developed large blooms in experimental Blooms of the cyanobacterium Nodularia spumigena occur regularly in the Baltic Sea typically producing a wide range of bioactive peptides including the hepatotoxin nodularin (NOD), spumigins, anabaenopeptins and nodulopeptins (molecular weights: 917, 901 and 899 Da).

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).

Some cells are modified to have various functions, such as nitrogen-fixing cells (heterocysts). It also produces thick-walled resting stages called akinetes (spores).
