Rapid Detection of Toxin-Producing Cyanobacteria

2020
Lake 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.

[Cyanobacteria, their toxins and health risks].

Medecine tropicale : revue du Corps de sante colonial, 1996
Cyanobacteria (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.

The mechanisms of ozonation on cyanobacteria and its toxins removal

Separation and Purification Technology, 2009
Abstract 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.

Biochemical Method for Quantitative Estimation of Cyanobacteria Toxins

2008
It 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

Toxin production of cyanobacteria is increased by exposure to zooplankton

Freshwater Biology, 2003
Summary1. 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

Toxins of freshwater cyanobacteria.

Microbiological sciences, 1990
Animal 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.

Investigation of a novel toxin produced by a Limnothrix cyanobacteria

2017
Limnothrix is a common genera of cyanobacteria that has previously shown very limited evidence as a producer of toxic metabolites. Recently, a species of Limnothrix cyanobacteria has been shown to be the producer of an unusual cyanobacterial toxin (the toxin suppresses cellular ATP production and inhibits protein synthesis).

Health Effects of Toxin-Producing Cyanobacteria: “The CyanoHABs”

Human and Ecological Risk Assessment: An International Journal, 2001
Increasingly, 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 ...
