Although none of the bacterial isolates showed strong algicidal effect, the observed stimulatory and retarding effects on N. spumigena growth under culture conditions denotes the importance of the associated bacterial community for the dynamics of these cyanobacterial populations in nature. 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. Nodularia spumigena is one of the dominating species during the extensive cyanobacterial blooms in the Baltic Sea. The blooms coincide with strong light, stable stratification, low ratios of dissolved inorganic nitrogen, and dissolved inorganic phosphorus. Nodularia spumigena is an estuarine cyanobacteria that produces the toxin nodularin. This toxic cyanobacteria is known to have caused death to domestic and wild animals and is recognised as dangerous to human health.

Nodularin is a tumor promoter known to have killed wild and domestic animals by seriously affecting the liver. It is a liver carcinogen due to the inhibition of protein phosphataes. The effects on T. weissflogii were more variable, and they were amplified by repeated filtrate additions compared to a single filtrate addition.
