The toxins of cyanobacteria.
On May 2, 1878, George Francis of Adelaide, Australia, published the Þrst scholarly description of the potentially lethal eÝects produced by cyanobacteriaÑthe microorganisms sometimes called blue-green algae or, more colloquially, pond scum. In a letter to Nature he noted that an alga he thought to be Nodularia spumigena had so proliferated in the estuary of the Murray River that it had formed ...
متن کاملNatural Toxins from Cyanobacteria
Morphologically, physiologically and metabolically, cyanobacteria (blue-green algae) are one of the most diverse groups of prokaryotes. Cyanobacteria bloom abundantly in surface waters as a result of eutrophication, and they produce different types of toxins, so they not only hinder recreational use of bodies of water but also cause health problems in humans and animals. Cyanobacterial toxins (...
متن کاملCyanobacteria toxins in the Salton Sea
BACKGROUND The Salton Sea (SS) is the largest inland body of water in California: surface area 980 km2, volume 7.3 million acre-feet, 58 km long, 14-22 km wide, maximum depth 15 m. Located in the southeastern Sonoran desert of California, it is 85 m below sea level at its lowest point. It was formed between 1905 and 1907 from heavy river flows of the Colorado River. Since its formation, it has ...
متن کاملCyanobacteria Toxins: Diversity and Ecological Effects
Cyanobacteria are known to produce secondary metabolites which are toxic to mammals, commonly known as “toxins”. These have been described as having neurotoxic, hepatotoxic and dermatotoxic effects, being a hazard also to humans. Cyanobacteria blooms may represent a hazard to aquatic organisms, when cells collapse, releasing cyanotoxins to the water. Toxins, though, have a dramatic influence on...
متن کاملStudy on destruction of extracted toxins from isolated Cyanobacteria using titanium dioxide
Cyanobacteria are major group of microorganism with capability to produce different types of toxin. Indeed, anthropogenic eutrophication of surface water is the main reason for acceleration of their growth and ecological problems. Therefore, the present study tried to isolate toxic cyanobacteria from Kor River, Fars province. For this purpose, 18 water samples were collected from three sampling...
