organism, limits the growth of algae and cyanobacteria. Nodularia spumigena. Mertens is a blue-green algae species inhabiting the Baltic region that often forms.

Summary 11 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 Individual Nodularia spumigena cells are oval, compressed …

The intensity of algal blooms has increased during the past decades in the Baltic Sea region, thus increasing the risk for intoxications in domestic and wild animals. 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 the biota in the surface water due to the natural buoyancy of this species.

The ecological role of nodularin in cyanobacterium Nodularia spumigena is still largely unknown, as are the conditions that promote toxin production. We report a modulating effect of mesozooplankton grazing on cellular nodularin content in N. spumigena expressed as a decrease in cell-bound toxin concentration in the presence of copepods compared with the cyanobacterium in similar assemblages

Entrez records. The bloom-forming cyanobacterium Nodularia spumigena CENA596 encodes the biosynthetic gene clusters (BGCs) of the known natural products nodularins, spumigins, anabaenopeptins/namalides, aeruginosins, mycosporin-like amino acids, and scytonemin, along with the terpenoid geosmin. Targeted metabolomics confirmed the production of these metabolic compounds, except for the alkaloid scytonemin. Nodularin is a potent hepatotoxin produced by the algal species Nodularia spumigena. The intensity of algal blooms has increased during the past decades in the Baltic Sea region, thus increasing the risk for intoxications in domestic and wild animals.

Nodularin is a potent hepatotoxin produced by the algal species Nodularia spumigena. The intensity of algal blooms has increased during the past decades in the Baltic Sea region, thus increasing the risk for intoxications in domestic and wild animals.

It also produces thick-walled resting stages called akinetes (spores). 2011-08-01 Bloom conditions were simulated in a mesocosm by adding a high concentration of cultured hepatotoxic Nodularia spumigena to 100 mm filtered natural sea water. 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 Abstract. A bloom of Nodularia spumigena Mertens occurred in Orielton Lagoon, Tasmania, a shallow, eutrophic coastal embayment, between December 1992 and March 1993. The N. spumigena bloom was preceded by a eustigmatophyte bloom and was followed in March-April 1993 by a bloom of the diatoms Nitzschia closterium (Ehrenb.) Smith and Chaetoceros socialis Lauder.
