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.

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 ...

Biodegradation of microcystin-LR using acclimatized bacteria isolated from different units of the drinking water treatment plant [PDF]

, 2018
Bacterial community isolated from different units of a Drinking Water Treatment Plant (DWTP) including pre-ozonation unit (POU), the effluent-sludge mixture of the sedimentation unit (ESSU) and top-sand layer water sample from the filtration unit (TSFU ...

Bacteria homologus to Aeromonas capable of microcystin degradation [PDF]

, 2014
Water blooms dominated by cyanobacteria are capable of producing hepatotoxins known as microcystins. These toxins are dangerous to people and to the environment. Therefore, for a better understanding of the biological termination of this increasingly

Oxidative stress biomarkers in Clarias gariepinus (Burchel, 1822) exposed to Microcystin-LR

Beni-Suef University Journal of Basic and Applied Sciences, 2017
Stress levels inflicted by microcystin-LR extracted from Microcystis aeruginosa were assessed by estimating the effects on the oxidative stress biomarkers in the liver, muscle and gill tissues of Clarias gariepinus. Microcystin-LR was administered to the

Cloning and expression of first gene for biodegrading microcystins by Sphingopyxis sp. USTB-05 [PDF]

, 2010
Harmful cyanobacterial blooms (HCBs) in natural waters are a growing environmental problem worldwide because microcystins (MCs) produced by cyanobacteria are potent hepatotoxins and tumor promoters. MCs are resistant against physical and chemical factors.

Exploring the direct effects of microcystin-LR on DNA via using cross-technical means

Ecotoxicology and Environmental Safety, 2022
Microcystin-leucine arginine (MC-LR) is the most toxic and abundant microcystin produced by cyanobacteria. Previous studies have demonstrated that MC-LR can lead to DNA damage by increasing intracellular reactive oxygen species content to induce ...

Combined and single effects of pesticide carbaryl and toxic Microcystis aeruginosa on the life history of Daphnia pulicaria [PDF]

, 2010
The combined influence of a pesticide (carbaryl) and a cyanotoxin (microcystin LR) on the life history of Daphnia pulicaria was investigated. At the beginning of the experiments animals were pulse exposed to carbaryl for 24 h and microcystins were ...

Microcystin-LR Induces Alterations in Heart Muscle

Folia Biologica, 2006
MC-LR belongs to a family of cyanobacterial toxins. MC-LR acts as serine-threonine phosphatase-1 and -2A inhibitor. Chronic intoxication with low doses of this toxin promotes liver tumour formation and induces kidney injury. The aim of the study was to evaluate whether chronic exposure to relatively low doses of MC-LR has toxic effects on hearts of ...

Proteasome as a Molecular Target of Microcystin-LR [PDF]

Toxins, 2015
Proteasome degrades proteins in eukaryotic cells. As such, the proteasome is crucial in cell cycle and function. This study proved that microcystin-LR (MC-LR), which is a toxic by-product of algal bloom, can target cellular proteasome and selectively inhibit proteasome trypsin-like (TL) activity. MC-LR at 1 nM can inhibit up to 54% of the purified 20S
