Cyanobacteria are ancient prokaryotes responsible for bloom formation in many freshwater resources worldwide. These dense agglomerations a result of the rise nutrient input (N and P) or temperature. The toxin content illness associated with contact impair human health repercussions water quality. Produced by wide variety cyanobacteria species, CyanoBlooms need literature review to achieve globa...

Cyanobacteria's long evolutionary history has enabled them to adapt to geochemical and climatic changes, and more recent human and climatic modifications of aquatic ecosystems, including nutrient over-enrichment, hydrologic modifications, and global warming. Harmful (toxic, hypoxia-generating, food web altering) cyanobacterial bloom (CyanoHAB) genera are controlled by the synergistic effects of...

This paper describes emerging issue related to cyanobacterial dynamics and toxicity and human health risks. Data show an increasing cyanobacteria expansion and dominance in many environments. However there are still few information on the toxic species fitness, or on the effects of specific drivers on toxin production. Open research fields are related to new exposure scenario (cyanotoxins i...

The frequency and intensity of toxic cyanobacterial blooms in drinking water sources is an increasing issue. The unpredictability of such blooms would make real-time detection methods a potential tool to help to manage the problem. This study therefore aims to investigate the difficulties associated with commercially available in vivo cyanobacteria fluorescence probes and assess the applicabili...

The carbon isotope composition of photosynthetic organisms reflects the (delta)(sup13)C of their inorganic carbon sources. The large difference between (delta)(sup13)C in cyanobacterial surface scums (-25 to -18(permil)) and subsurface blooms (-34 to -30(permil)) in a subarctic lake indicates direct atmospheric CO(inf2) fixation by the scums.
