Thus far, the negative effects of Nodularia spumigena blooms on aquatic organisms have been mainly attributed to the production of the hepatotoxic nodularin (NOD). In the current work, the accumulation of other N. spumigena metabolites in blue mussels and crustaceans, and their effect on Thamnocephalus platyurus and Artemia franciscana, were examined.

was found to produce a potent hepatotoxic peptide (50% lethal intraperitoneal dose for the mouse, 60 micrograms/kg) with chemical and toxicological properties similar to those of the hepatotoxic heptapeptides produced by other freshwater planktonic cyanobacteria. Stimulating effects of added iron were more pronounced at continuously high incident irradiance. A bi-directional approach of iron manipulation comprising either iron or siderophore addition revealed a medium level of iron starvation in near-coast Nodularia bloom material. Significant stimulation of the quantum efficiency of photosystem II (up to 100%) also indicated photosynthetic performance as a main target of iron fertilization. Effects of NODLN on FlounderThe administration of NODLN by force-feeding into flounder, either as a single high dose 4 days before sampling or as three smaller doses 3 days apart, clearly caused some hepatocellular damage. Three filamentous and heterocystous cyanobacterial strains of Nodularia, Nodularia baltica, Nodularia harveyana and Nodularia spumigena, have been tested for the presence and induction of ultraviolet-absorbing/screening mycosporine-like amino acids (MAAs) by simulated solar radiation in combination … The bacterial strain B 30, added at different concentrations to the N. spumigena cultures, showed a negative, retarding effect at all concentrations used, ranging from a 10% lower cyanobacterial biomass yield relative to controls at 5×10 2 bacterial cells ml −1 up to 30% at 5×10 7 bacterial cells ml −1 ( Fig. 5 ).

The highest decline in growth, as well as the most apparent cell physical damage, was observed for the diatom S. marinoi. 2002-12-03 In the presence of ammonium ion, Nodularia spumigena strain AV1, a filamentous, heterocystous cyanobacterium isolated from the Baltic Sea, lost aerobic nitrogen-fixation activity while maintaining heterocyst frequency along the filaments. METHOD Sampling and test organisms This study consisted of two experiments designed to test the effects of grazing on nodularin concentrations and reciprocal effects of Nodularia spumigena on mortality and growth of the grazers.

The N. spumigena laboratory strain AV1 was isolated from a Baltic Sea cyanobacterial bloom in August 1987 (Lehtimäki 2000). Request PDF | Nodularia spumigena Peptides-Accumulation and Effect on Aquatic Invertebrates | Thus far, the negative effects of Nodularia spumigena blooms on aquatic organisms have been mainly 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 growth of Nodularia spumigena and the related ﬂuxes of car-bon, nitrogen, and phosphorus. In particular we wanted to investigate the effect of ocean acidiﬁcation on the exudation of organic matter and its subsequent recycling by extracel-lular enzymes in a Nodularia spumigena batch experiment.

Introduction NOD was first isolated from Nodularia spumigena, a cyanobacterium that is Nodularia spumigena is a filamentous cyanobacterium that is commonly found in especially in the Baltic Sea, we have investigated the effect of nitrate and Long-term effects on feeding and survival remain to be studied, especially for the and Nodularia spumigena, to the sediment was earlier considered negligible Gimbel, H.

The effects on growth, fluorescence parameter (Fv/Fm) and the photosynthetic parameter. (Pm) of N. spumigena were amplified by repeated filtrate additions of (32) showed that the edible mussel (M.

N. spumigena produces the hepatotoxin, nodularin (Rinehart et al., 1988), and has been reported to affect aquatic and terrestrial animals (Landsberg, 2002). A. flos-aquae and Anabaena spp. are generally not toxic in the Baltic Sea (Sivonen et al., 1989). In freshwater environments, in contrast, both genera produce toxins (Landsberg, 2002).
