Uptake and accumulation of dissolved, radiolabeled nodularin in Baltic Sea zooplankton

Environmental Toxicology, 2003
AbstractThe mass occurrence of toxic cyanobacteria is a recurrent phenomenon in the Baltic Sea. Grazers may obtain toxins either through ingestion or by direct exposure to dissolved toxins. Despite this, there is little knowledge about the accumulation of cyanobacterial toxins in planktonic organisms present during these blooms.

ChemInform Abstract: Nodularin, Microcystin, and the Configuration of Adda.

ChemInform, 1989
AbstractThe uniquely characteristic C20 amino acid Adda is present in closely related toxins reported recently such as microcystins (cyanoginosins; all cyclic heptapeptides), e.g. microcystin LR (I) (presumably identical with cyanoginosin LR).

Heterogeneity of nodularin bioaccumulation in northern Baltic Sea flounders in 2002

Chemosphere, 2005
The cyanobacterial hepatotoxin nodularin is abundantly produced by the cyanobacterium Nodularia spumigena in the Baltic Sea during July-August. Nodularin is a potent hepatotoxin and a tumour promoter, distributed in various Baltic Sea environmental compartments, especially food webs involving mussels.

Effects of Nutrients on Growth and Nodularin Production of Nodularia Strain GR8b

Microbial Ecology, 2001
To determine the effects of nutrients on growth and toxin production of Nodularia strain GR8b, several nutrient concentrations were tested in batch and chemostat cultures. In batch cultures, phosphate (55-5,500 mg L-1) and nitrate (100-30,000 mg L-1) concentrations were applied, whereas in chemostat cultures, phosphate concentrations (5-315 mg L-1 ...

Nodularin uptake and induction of oxidative stress in spinach (Spinachia oleracea)

Journal of Plant Physiology, 2011
The bloom-forming cyanobacterium Nodularia spumigena produces toxic compounds, including nodularin, which is known to have adverse effects on various organisms. We monitored the primary effects of nodularin exposure on physiological parameters in Spinachia oleracea.

A fluorescent immunochromatographic test using immunoliposomes for detecting microcystins and nodularins

Analytical and Bioanalytical Chemistry, 2009
Microcystins (MCs), a group of cyclic heptapeptides produced by common cyanobacteria (blue green algae), cause both acute and chronic toxicity. Due to their toxicity, constant monitoring in drinking water, recreational waters as well as other potential exposure through ingestion of contaminated sea food, is very important.

Nodularin from benthic freshwater periphyton and implications for trophic transfer

Toxicon, 2017
In 2013 and 2015, the Pennsylvania Department of Environmental Protection conducted a survey of lotic habitats within the Susquehanna, Delaware, and Ohio River basins in Pennsylvania, USA, to screen for microcystins/nodularins (MCs/NODs) in algae communities and smallmouth bass (Micropterus dolomieu). Periphyton (68 from 41 sites), juvenile whole fish (
