First Report of Microcystis Strains Producing MC-FR and -WR Toxins in Japan

, 2019
Microcystins (MCs) are a group of cyclic heptapeptide hepatotoxins produced by Microcystis and several other genera of cyanobacteria. Many structural variants have been characterized using various methods such as liquid chromatography–mass ...

Citrus depressa peel extract and its polymethoxyflavones mitigate acetaminophen‐induced chronic liver injury in mice through antioxidant activation, epigenetic regulation, and gut microbiota modulation

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7629-7642, October 2026.
Abstract BACKGROUND Preventing chronic liver damage is essential for maintaining overall health and reducing the risk of serious liver diseases. Acetaminophen (APAP) overdose can lead to severe liver damage due to oxidative stress, and citrus fruits are rich in bioactive compounds that may have health benefits.

Intrinsic Disorder as a New Frontier in Antimicrobial Resistance and Bacterial Fitness

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The works examines the link between intrinsic disorder in bacterial protein structure, and bacterial function, and antimicrobial resistance. It highlights how flexible, disordered proteins support secretion, stress responses, desiccation protection, and virulence, while also suggesting that these adaptable regions may provide novel targets for ...

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, Volume 41, Issue 10, Page 889-905, October 2026.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, Volume 41, Issue 10, Page 1060-1068, October 2026.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

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 ...

Correlations Between a Cyanobacteria Bloom's Decline and Environmental Dynamics. [PDF]

, 2009
Lake Kainui is an ombrogenous peat lake that is eutrophic and has frequent cyanobacterial blooms. This research aimed to elucidate the factors that correlated with cyanobacterial bloom decline in Lake Kainui. Abiotic and biotic variables in Lake Kainui
