En av de dominerande blommande arterna var blågrönalgen Nodularia spumigena som konstaterats vara giftig. Blomningama var en följd blå-grönalgen Nodularia spumigena. Dessa ”mördaralger” är egentligen cyanobakterier som trivs i bräckt vatten.

När katthårsalgen, Nodularia, blommar bildar den långa kedjor av celler som ser ut som rabarbersoppa. Det är främst dessa algblomningar som kan vara giftiga för djur och barn som råkar få i sig mycket av vattnet. Det finns fem arter av nodularia i Östersjön, men det är endast Nodularia spumigena, som finns i hela Östersjön. Nodularia spumigena blommar och täcker stora delar av Östersjön.

Nodularia spumigena UHCC 0039 Nodularia spumigena UTEX B 2092 Disclaimer: The NCBI taxonomy database is not an authoritative source for nomenclature or classification - please consult the relevant scientific literature for the most reliable information.

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. 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).

Algblomning i vattnet vid Nodularia spumigena is a toxic cyanobacteria that blooms in the Baltic Sea every year. In the brackish water of the Baltic Sea, its toxin, nodularin, mainly affects Nodularin (Nod), produced by the brackish/marine cyanobacterium Nodularia spumigena, is a potent hepatotoxin, tumor promoter and is possibly carcinogenic Nodularia spumigena is a toxic, filamentous cyanobacterium occurring in brackish waters worldwide, yet forms extensive recurrent blooms in the Baltic Sea. av F Eriksson · 2013 — Salinity impact on cyanobacteria toxicity in Nodularia spumigena gene expression of ndaF in two N. spumigena strains, KAC11 and KAC66. av M Malin · 2010 · Citerat av 3 — Intraspecific variation in the response of the cyanobacterium Nodularia spumigena to moderate UV-B radiation.

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

We recognize the great potential for phytoplankton products to yield renewable energy resources, and the impacts that may have for economic and ecological sustainability.

2007-04-01 2018-09-01 Batch cultures of Nodularia spumigena were grown for 15 days under aeration with low (180 μatm), medium (380 μatm), and high (780 μatm) CO 2 concentrations. Obtained pCO 2 levels in the treatments were on median 315, 353, and 548 μatm CO 2, respectively. Nodularia Spumigena What is Nodularia? Nodularia is a blue-green alga (also known as cyanobacteria). It produces chains of cells to form mostly straight filaments. Some cells are modified to have various functions, such as nitrogen-fixing cells (heterocysts). It also produces thick-walled resting stages called akinetes (spores).
