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

The effects of changes in diurnal light patterns, salinity, and phosphorus on nitrogen fixation (as measured by acetylene reduction) by Nodularia spumigena Mertens were examined. As well, the effects of added inorganic nitrogen on growth, nitrogen fixation and heterocyt frequencies, and changes in nitrogen fixation and heterocyst frequencies during the growth cycle of Nodularia in cultures

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 producerar mest gift när det är lite kväve i vattnet men tillräckligt mycket fosfor, säger Malin Mohlin på Institutionen för marin ekologi vid Göteborgs universitet. Det innebär till exempel att om avloppsvatten i huvudsak renas från kväve, kan det leda till mer gift i blomningarna. 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. 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 production of aeruginosins by N. spumigena was revealed in Assignment to the species Nodularia spumigena is preliminary. Comments of the depositor: "Nodularia is a diazotrophic filamentous cyanobacterium. Nodularia spumigena is a nitrogen-fixing cyanobacterium that forms toxic blooms in the Baltic Sea each summer and the availability of phosphorous is an important factor limiting the formation of We investigated the effects of addition of dissolved organic matter (DOM) on the growth and chemical composition of Nodularia spumigena cells under conditions of P or N deficiency. Semi-continuous monocultures of N. spumigena Mertens were established. Bloom conditions were simulated in a mesocosm by adding a high concentration of cultured hepatotoxic Nodularia spumigena to 100 mm filtered natural sea water. This seston was fed to copepods at days 1, 7, and 14 from the start of the mesocosm experiment, when it consisted of actively growing cyanobacteria (days 1 and 7) and increasing amounts of heterotrophic organisms and probably detritus 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.
