Hepatotoxins were thus probably not involved in the allelopathic effects, which is also indicated by the allelopathic properties of the non-toxic A. flos-aquae and A. lemmermannii. 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. In Expt I, N. spumigena was incubated in natural, 90 m m plankton with (12–33 ind. L 2 1) or without copepods. A clonal isolate, termed L575, of the filamentous brackish-water cyanobacterium Nodularia spumigena Mertens emend.

2003-10-01 · Effect on Nodularia spumigena KAC13 Dissimilar responses were observed following the addition of the bacterial isolates into exponentially growing N. spumigena cultures. Before the addition of the bacteria, the N. spumigena biomass, expressed as in vivo chlorophyll a fluorescence, was identical among all treatments and controls. Abstract.

how different species of macrozoobenthos can affect the recruitment of Nodularia spumigena from the sediment to the water column. N. spumigena is a toxic, nitrogen-fixing filamentous cyanobacterium, which forms large summer blooms in the Baltic Sea. Benthic recruitment from resting stages Effect of irradiance, temperature and salinity on growth and toxin production by Nodularia spumigena N. spumigena was more allelopathic in exponential than in stationary growth phase, whereas the culture filtrate was more hepatotoxic in stationary phase.

high The object of this work was to determine, using a full-factorial experiment, the influence of temperature, irradiance and salinity on growth and hepatotoxin production by Nodularia spumigena, isolated from Lake Alexandrina in the south-east of South Australia.
