Initial Assessment of the Detectability of Cyanotoxin Occurrence Using PACE Satellite Observations

Geophysical Research Letters
Microcystin is a major public health hazard during freshwater cyanobacterial blooms, yet its remote detection remains challenging because it lacks any direct optical absorption features.

A Review of Nephrotoxicity of Microcystins [PDF]

Toxins, 2020
Cyanobacterial blooms triggered by eutrophication and climate change have become a global public health issue. The toxic metabolites microcystins (MCs) generated by cyanobacteria can accumulate in food chain and contaminate water, thus posing a potential threat to human and animals health.

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]

, 2012
An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

simpson-lab/quappelle-microcystin-paper: Updated data and script

, 2021
There was an inconsistency between the microcystin variable named in the data files and assumed in the main data analysis script. In addition, the raw microcystin data were uploaded but we actually used a censored version wherein all observations that ...

Effects of lake warming on the seasonal risk of toxic cyanobacteria exposure

Limnology and Oceanography Letters, 2020
Incidence of elevated harmful algal blooms and concentrations of microcystin are increasing globally as a result of human‐mediated changes in land use and climate.

The cyanobacterial hepatotoxin microcystin binds to proteins and increases the fitness of microcystis under oxidative stress conditions. [PDF]

PLoS ONE, 2011
Microcystins are cyanobacterial toxins that represent a serious threat to drinking water and recreational lakes worldwide. Here, we show that microcystin fulfils an important function within cells of its natural producer Microcystis.

Chirality in microcystins [PDF]

Journal of the American Society for Mass Spectrometry, 1994
A new method has been developed to identify the isomers of amino acids by derivatization of the corresponding standards with 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide (Marfey's reagent or FDAA) and analysis of the diastereomeric derivatives by a liquid chromatography-thermospray mass spectrometry technique.

Widespread distribution and identification of eight novel microcystins in Antarctic cyanobacterial mats [PDF]

, 2008
The microcystin content and cyanobacterial community structure of Antarctic microbial mat samples collected from 40 ponds, lakes and hydro-terrestrial environments were investigated. Samples were collected from Bratina Island and four of the Dry Valleys;

Temporal Dynamics of the Microbial Community Composition with a Focus on Toxic Cyanobacteria and Toxin Presence during Harmful Algal Blooms in Two South German Lakes

Frontiers in Microbiology, 2017
Bacterioplankton plays an essential role in aquatic ecosystems, and cyanobacteria are an influential part of the microbiome in many water bodies. In freshwaters used for recreational activities or drinking water, toxic cyanobacteria cause concerns due to

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...
