Because of recurring events associated with global climate changes, several combined factors have been favored formation of toxic cyanobacteria blooms and increase of cyanotoxins production. Microcystins (MC) are cyanotoxins widely distributed in drinking water sources all over the world, with a story of several human intoxication cases and deaths. In this regard, it is endowed with great…
Cyanobacteria are photosynthesizers organisms naturally occurring in aquatic ecosystems. However, the escalating eutrophication of these environments has been causing ecological unbalance and excessive growth of such organisms. Cyanobacteria are producers of several toxins, microcystins and cilindrospermopsins among them, which can induce intoxication and death in mammals, humans inclusiv…
Allelophathic effects are biochemical interactions, from stimuli as from inhibition, among different primary producers. The hypothesis by which cyanotoxins have allelophatic action was not yet confirmed since results so far obtained are controversial, once the tested toxin concentrations are not usual in the aquatic environment. This study aims at the evaluation of allelophathic effects o…

Interactions between cyanobacteria and their environment result in the production of secondary metabolites that are classified as being allelochemicals and toxins. These are geared towards ensuring their cell proliferation in the aquatic system and out competing neighboring micro- and macro-plants and cyanobacteria for available nutrients and space. Among the cyanotoxins produced by speci…
Temperature and UV radiation are important factors that regulate bloom forming cyanobacteria, cyanotoxins production and carbon dioxide (CO2) sequestration in aquatic ecosystems. Due to changing global climatic conditions, investigations of physiological during the production of microcystins and sequestration of CO2 are urgently needed. The aim of the proposed study is to evaluate the com…
The physiological and molecular processes defining interspecific interactions of various phytoplankton species are still not presently understood in quantitative terms. Most co-culture experiments have been very restricted methodologically and in most cases limited to cell counts, biovolume and growth rate determinations, which are not sufficient to explain phytoplankton successional proc…
