Characteristics of a Microcystin-Degrading Bacterium under Alkaline Environmental Conditions [PDF]

open access: yesJournal of Toxicology, 2009
The pH of the water associated with toxic blooms of cyanobacteria is typically in the alkaline range; however, previously only microcystin-degrading bacteria growing in neutral pH conditions have been isolated.

Degradation of microcystin-LR by aquatic bacteria. [PDF]

open access: yes, 2007
Microcystins are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions.

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

open access: yes, 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 ...

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

open access: yes, 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;

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

open access: yesLimnology 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]

open access: yesPLoS 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.

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

open access: yes, 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 ...

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

open access: yesFrontiers 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]

open access: yes, 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 ...

Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands

open access: yesToxins, 2013
In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g−1 dry-weight microcystin, the vomit of one of ...
