On May 2, 1878, George Francis of Adelaide, Australia, published the Þrst scholarly description of the potentially lethal eÝects produced by cyanobacteriaNthe 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 ...

Degradation of cyanobacteria toxin by advanced oxidation processes
Journal of Hazardous Materials, 2008Advanced oxidation processes (AOPs) using O(3), H(2)O(2), O(3)/H(2)O(2), O(3)/Fe(II), and Fenton treatment were investigated for the degradation of aqueous solutions of cyanobacteria. The effects of concentration of reactants, temperature, and pH on toxins degradation were monitored and the reaction kinetics was assessed.

Knowledge about the impact of singlet oxygen (1O2) on the characteristics and inactivation of harmful cyanobacterial organic matter is limited. In this study, the feasibility of using an improved single-iron doped graphite-like phase carbon nitride ...

The Genetic Basis of Toxin Production in Cyanobacteria
Freshwater Reviews, 2009The increasing incidence of mass developments of Cyanobacteria in fresh- and brackish water is a matter of growing concern due to the production of toxins that threaten human and livestock health. The toxins that are produced by freshwater Cyanobacteria comprise hepatotoxins (cyclic peptides such as microcystins and nodularin, as well as alkaloids such

A handbook of environmental toxicology: human disorders and ecotoxicology, 2020
Cyanobacteria are capable of producing a wide range of low-molecular-weight toxic compounds, largely identified as a result of poisoning incidents and through meticulous screening of cyanobacterial strains and blooms. Their molecular modes of action vary

Advances in genomics, transcriptomics and proteomics of toxin‐producing cyanobacteria
Environmental Microbiology Reports, 2016Summary A common misconception persists that the genomes of toxic and non‐toxic cyanobacterial strains are largely conserved with the exception of the presence or absence of the genes responsible for toxin production. Implementation of ‐omics era technologies has challenged this paradigm, with comparative analyses providing increased ...

Cyanobacteria and toxins detection. A review
2023Water environment eutrophication increases the risk of harmful bloom development, like cyanobacterial blooms, which can produce potent toxins able to affect public and animal health. More than 50% of the cyanobacterial proliferation are toxic. Both toxigenic (toxin producers) and non-toxigenic strains, may exist within a single specie of cyanobacteria.

Trends in Biological Degradation of Cyanobacteria and Toxins
2011Cyanobacteria are known as blue-green algae, blue-green bacteria, and Cyanophyta. They are present in both toxic and non-toxic forms and it is actually the toxic form which proliferates in the aquatic environment. There are principally two types of toxins (neurotoxin and hepatotoxin) which lead to adverse environmental and human health impacts.

Rapid Detection of Toxin-Producing Cyanobacteria
2020Lake Mead provides drinking water to millions of people in Nevada, California, and Arizona. In 2015, the Southern Nevada Water Authority detected the cyanobacteria-produced toxin microcystin in the lake for the very first time. This toxin is lethal in large doses, and in small doses it causes a myriad of serious health effects.
