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 ...

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.

Toxin production of cyanobacteria is increased by exposure to zooplankton
Freshwater Biology, 2003Summary1. Cyanobacterial toxin production in response to direct and indirect zooplankton feeding activity was examined using four strains of Microcystis aeruginosa, of which three were previously reported to be toxic to zooplankton and one non‐toxic. Direct (Microcystis cultured with zooplankton) and indirect effects (Microcystis cultured with filtered

The mechanisms of ozonation on cyanobacteria and its toxins removal
Separation and Purification Technology, 2009Abstract In the present study, the effect of ozone (O 3 ) as preoxidant for algae-laden source water, and the mechanisms that it causes algal cells broken and intracelluar cytoplasm release with its influence on microcystins (MC-LR, MC-RR) removal were investigated.

[Cyanobacteria, their toxins and health risks].
Medecine tropicale : revue du Corps de sante colonial, 1996Cyanobacteria (blue-green algae) commonly occur in fresh and brackish water where they produce blooms under certain environmental and climatic conditions. Since some species produce neurotoxins, hepatotoxins, cytotoxins, and endotoxins, blooms can be hazardous for animal and human health.

Biochemical Method for Quantitative Estimation of Cyanobacteria Toxins
2008It is shown the possibility of using the model reaction with cholinesterase inhibition for qualitative and quantitative determination of Cyanobacteria toxic metabolites in natural waters and algae cells. It was established that changes of cultural medium pH may be registered by spectrophotometric method with using of bromine thymol blue indicator or by

Toxins of freshwater cyanobacteria.
Microbiological sciences, 1990Animal deaths after drinking water containing toxic cyanobacteria have been known for over a century. Poisonings occur annually and the fate of the toxins in natural and man-made waters is unknown. This article reviews the formation, properties and effects of freshwater cyanobacterial toxins.

Health Effects of Toxin-Producing Cyanobacteria: “The CyanoHABs”
Human and Ecological Risk Assessment: An International Journal, 2001Increasingly, harmful algal blooms (HABs) are being reported worldwide due to several factors, primarily eutrophication, climate change and more scientific monitoring. All but cyanobacteria toxin poisonings (CTPs) are mainly a marine occurrence. CTPs occur in fresh (lakes, ponds, rivers and reservoirs) and brackish (seas, estuaries, and lakes) waters ...
