Toxins, 2023 Microcystin can be present in variable concentrations, phases (dissolved and particulate), and structural forms (congeners), all which impact the toxicity and persistence of the algal metabolite.

Transgenerational effects of microcystin-LR onDaphnia magna [PDF]
Journal of Experimental Biology, 2012 SUMMARYAnthropogenic and climate factors increase the frequency of problematic cyanobacterial blooms in freshwater. Among other toxins, some cyanobacteria produce microcystins (MCs), which inhibit phosphatases type 1 and type 2A and provokes oxidative stress.

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;

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 ...

Use of Myriophyllum aquaticum to inhibit Microcystis aeruginosa growth and remove microcystin-LR
Revista Brasileira de Ciências Ambientais, 2022 Harmful algal blooms are one of the greatest challenges when preserving water sources, especially when involving cyanobacteria such as Microcystis aeruginosa.

Biomarkers of prolonged exposure to microcystin-LR in mice [PDF]
Toxicon, 2013 The effects of prolonged exposure to microcystins (MCs) on health are not yet sufficiently understood and this type of poisoning is often undiagnosed. Even though chronic exposure has been linked with liver cancer and alterations have been described in liver damage marker enzymes in exposed populations, there are not profile parameters that indicate ...

Epitopes prediction for microcystin-LR by molecular docking
Ecotoxicology and Environmental Safety, 2021 Microcystin-LR (MC-LR) is one of the most worldwide harmful cyanobacterial toxins. A lots of antibodies against MC-LR have been generated and characterized. However, the knowledge about the epitopes of MC-LR was still limited. The objective of this study was to analyze the epitopes of MC-LR and demonstrate the binding mode of MC-LR with its antibody ...

Journal of Venomous Animals and Toxins including Tropical Diseases, 2015 Background Toxic cyanobacterial blooms are recurrent in Patos Lagoon, in southern Brazil. Among cyanotoxins, [D-Leu1] microcystin-LR is the predominant variant whose natural cycle involves water and sediment compartments. This study aimed to identify and

Photorelease of microcystin-LR from resuspended sediments [PDF]
Harmful Algae, 2017 A series of ten photolysis experiments was conducted with sediments exposed to Microcystis sp. blooms to determine if sunlight is capable of mobilizing the biotoxin microcystin-LR (MC-LR) into the water column. There was a net photorelease of MC-LR in irradiated suspensions in all cases relative to dark controls, ranging from 0.4 to 192μgL-1g-1 into ...
