Både Aphanizomenon sp. och Nodularia spumigena* var mycket vanliga, men aggregeringar av blekta N. spumigena och Anabaena sp. fanns i störst mängd i det integrerade provet (0-10 m). En klorofyllfluorescenstopp på 15 meters djup dominerades av P. lauterbornii, Anabaena sp. och Aphanizomenon sp. och dinoflagellaten Dinophysis norvegica*.

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

Nodularia spumigena is a bloom-forming, ﬁlamentous and N2-ﬁxing cyanobacterium from the Nostocales order. This species occurs in many brackish waters worldwide, but most extensive blooms are reported in estuaries, lagoons and inland waters of Australia and New Zealand [1–3], and the

Salinity is an important abiotic factor controlling the distribution and abundance of Nodularia spumigena, the dominating diazotrophic and toxic phototroph, in the brackish water cyanobacterial blooms of the Baltic Sea. To expand the available genomic information for brackish water cyanobacteria, we sequenced the isolate Nodularia spumigena UHCC 0039 using an Illumina-SMRT hybrid sequencing 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.

In this study, changes in concentration of NOD and other NRPs during cyanophage infection of the filamentous cyanobacteria Nodularia spumigena were assessed using incubation experiments.

Nodularia spumigena Mertens, 1888 Ex Bornet and Flahaul Taxonomic Serial No.: 1227 (Download Help) Nodularia spumigena TSN 1227 Taxonomy and Nomenclature

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).

Det innebär till exempel att om avloppsvatten i huvudsak renas från kväve, kan det leda till mer gift i blomningarna. Two hepatotoxic Nodularia spumigena strains were isolated from the samples. The isolates produce a toxic peak indistinguishable from the bloom material in the HPLC analysis. 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. The ecological role of nodularin in cyanobacterium Nodularia spumigena is still largely unknown, as are the conditions that promote toxin production.
