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

Microcystins in water containers used in the home: A review of their potential health effects. [PDF]

, 2023
Cyanobacteria produce toxins that are harmful to humans. They are found mostly in surface water, which is the main water source for drinking water before treatment.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, Volume 41, Issue 10, Page 957-974, October 2026.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

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 ...

A Mini-Review on Detection Methods of Microcystins

Toxins, 2020
Cyanobacterial harmful algal blooms (CyanoHABs) produce microcystins (MCs) which are associated with animal and human hepatotoxicity. Over 270 variants of MC exist. MCs have been continually studied due of their toxic consequences.

Newly isolated strains of potentially microcystin-producing cyanobacteria in potable water: case study of Mawoni village, South Africa

Frontiers in Environmental Science
Toxic cyanobacterial species occur in aquatic ecosystems when favourable environmental conditions prevail. These bacteria can produce natural hepatotoxic metabolites called microcystins that can affect the quality of water. Human exposure to microcystins

A Mini Review on Microcystins and Bacterial Degradation

Toxins, 2020
Microcystins (MCs) classified as hepatotoxic and carcinogenic are the most commonly reported cyanobacterial toxins found in the environment. Microcystis sp.

Bacterial Contribution to Hydrogen Peroxide Decomposition in Lake Erie Cyanobacterial Harmful Algal Bloom Communities Is Dependent on Bloom Stage

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A seasonal time series metatranscriptome dataset suggests that neutralising hydrogen peroxide in Microcystis blooms requires a complex division of labour that is further complicated by seasonality and bloom development. ABSTRACT Cyanobacterial harmful algal blooms (cHABs) are expanding globally and often involve toxin‐producing species such as ...

Screening the toxicity and toxin content of blooms of the cyanobacterium Trichodesmium erythraeum (Ehrenberg) in northeast Brasil

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
Blooms of the cyanobacterium Trichodesmium occur in massive colored patches over large areas of tropical and subtropical oceans. Recently, the interest in such events has increased given their role in major nitrogen and carbon dioxide oceanic fluxes ...

How Epitranscriptomic Machinery Senses Environmental Cues

Advanced Biology, Volume 10, Issue 9, September 2026.
Exogenous exposures, microenvironmental signals, and intracellular metabolic or redox states can alter RNA‐modification machinery through catalytic chemistry, signaling‐dependent PTMs, compartmental redistribution, or changes in abundance and composition.
