Advances in genomics, transcriptomics and proteomics of toxin‐producing cyanobacteria

Environmental Microbiology Reports, 2016
Summary 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 ...

Toxins contained in Microcystis species of cyanobacteria (blue-green algae)

Toxicon, 1988
Cyclic peptide toxins were analyzed for three Microcystis species (M. aeruginosa, M. viridis and M. wesenbergii) using an ODS-silica gel cartridge and high performance liquid chromatography with ODS-silica gel. On strain of M. aeruginosa contained a high amount of microcystin (cyanoginosin) YR and a lesser amount of LR.

[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.

Trends in Biological Degradation of Cyanobacteria and Toxins

2011
Cyanobacteria 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.

pH-Dependent hydrophobicity of the cyanobacteria toxin microcystin-LR

Water Research, 1999
Abstract Although the presence of hepatotoxins in surface and drinking water is regarded as an ecotoxicological and human health problem, limited knowledge exists on the fate of these compounds. Therefore the n-octanol/water distribution ratio (Dow) of the hepatotoxin microcystin-LR (MC-LR) was determined in order to enable the prediction of the fate

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 ...

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.

Emerging high throughput analyses of cyanobacterial toxins and toxic cyanobacteria

2008
The common occurrence of toxic cyanobacteria causes problems for health of animals and human beings. More research and good monitoring systems are needed to protect water users. It is important to have rapid, reliable and accurate analysis i.e. high throughput methods to identify the toxins as well as toxin producers in the environment.
