First report of microcystins in Taiwan [PDF]
Toxicon, 1998 This is the first report on microcystins from Microcystis aeruginosa Kützing in Taiwan. A total of nine strains of cyanobacteria have been isolated from eutrophic aquaculture ponds and water reservoirs. By mouse toxicity assay, six of the nine strains had LD100 in the range of 25-100 mg per kg mouse for dried bacterial mass. Microcystin-LR and -RR were

Variations in the Microcystin Content of Different Fish Species Collected from a Eutrophic Lake
Toxins, 2013 Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of ...

Adsorption of microcystins by carbon nanotubes [PDF]
Chemosphere, 2006 The production of cyanobacterial toxins microcystins (MCs) by cyanobacterial bloom which may promote the growth of tumor in human liver is a growing environmental problem worldwide. In this paper, the adsorption of MC-RR and LR, which were extracted from cyanobacterial cells in Dianchi Lake in China, by carbon nanotubes (CNTs), wood-based activated ...

Purification and identification of microcystin-RR [PDF]
Chinese Journal of Chromatography, 2013 An effective method based on the combination of solid phase extraction and gel chromatography to extract and purify microcystin-RR (MC-RR) from natural cyanobacteria bloom was developed. Thirty five gram natural cyanobacterial bloom scum was extracted with 70% aqueous methanol. After the methanol in the crude extract was removed by a rotary evaporator,

Absence of Cyanotoxins in Llayta, Edible Nostocaceae Colonies from the Andes Highlands
Toxins, 2020 Edible Llayta are cyanobacterial colonies consumed in the Andes highlands. Llayta and four isolated cyanobacteria strains were tested for cyanotoxins (microcystin, nodularin, cylindrospermopsin, saxitoxin and β-N-methylamino-L-alanine—BMAA) using ...

A Review of Cardiovascular Toxicity of Microcystins [PDF]
Toxins, 2019 The mortality rate of cardiovascular diseases (CVD) in China is on the rise. The increasing burden of CVD in China has become a major public health problem. Cyanobacterial blooms have been recently considered a global environmental concern. Microcystins (MCs) are the secondary products of cyanobacteria metabolism and the most harmful cyanotoxin found ...

Microcystin mcyA and mcyE Gene Abundances Are Not Appropriate Indicators of Microcystin Concentrations in Lakes. [PDF]
PLoS ONE, 2015 Cyanobacterial harmful algal blooms (cyanoHABs) are a primary source of water quality degradation in eutrophic lakes. The occurrence of cyanoHABs is ubiquitous and expected to increase with current climate and land use change scenarios.

Effects of microcystin-LR in isolated perfused rat kidney
Brazilian Journal of Medical and Biological Research, 1999 Microcystin is a hepatotoxic peptide which inhibits protein phosphatase types 1 and 2A. The objective of the present study was to evaluate the physiopathologic effects of microcystin-LR in isolated perfused rat kidney.
