A Review of Common Cyanotoxins and Their Effects on Fish

Toxics, 2023
Global warming and human-induced eutrophication drive the occurrence of various cyanotoxins in aquatic environments. These metabolites reveal diversified mechanisms of action, encompassing cyto-, neuro-, hepato-, nephro-, and neurotoxicity, and pose a threat to aquatic biota and human health.

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Cyanotoxins: A Poison that Frees Phosphate [PDF]

Current Biology, 2010
Autotrophic organisms obtain phosphorus from the environment by secreting alkaline phosphatases that act on esters, resulting in inorganic phosphate that is then taken up. New work shows that the cyanobacterium Aphanizomenon ovalisporum obtains inorganic phosphate by secreting the cyanotoxin cylindrospermopsin, which induces alkaline phosphatase in ...

Limnofasciculus delicatus (Coleofasciculaceae, Coleofasciculales), a Novel Mat‐Forming Cyanobacterium From Shenandoah River, Virginia, USA

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
A novel mat‐forming benthic freshwater cyanobacterium, Limnofasciculus delicatus, is described based on morphological, phylogenetic and genomic evidence from the North and South Forks of the Shenandoah River. Although Limnofasciculus delicatus lacks biosynthetic gene clusters associated with the production of known cyanotoxins, it occurs in association

Cyanotoxins: A dermatological problem

Archive of Oncology, 2011
Cyanobacteria (blue-green algae), that are common inhabitants of water and terrestrial environments throughout the world, produce a broad spectrum of secondary metabolites - biologically active products that could be toxic (cyano?toxins). Scientific literature data unequivocally showed adverse effects of cyanotoxins on animal and human ...

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

Journal of Phycology, Volume 62, Issue 3, Page 801-817, June 2026.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

Ecological and molecular investigations of cyanotoxin production [PDF]

FEMS Microbiology Ecology, 2001
Cyanobacteria, broadly classified as oxygenic phototrophs containing chlorophyll- a and accessory pigments, are among the oldest life forms on earth. They may be unicellular, colonial or filamentous, with cell sizes varying from less than 2 μm to 40 μm in diameter. They may live as symbionts with plants and fungi, in the benthos or in the water column.

Human Illnesses and Animal Deaths Associated with Freshwater Harmful Algal Blooms—Kansas

Toxins, 2015
Freshwater harmful algal bloom (FHAB) toxins can cause morbidity and mortality in both humans and animals, and the incidence of FHABs in the United States and Kansas has increased. In 2010, the Kansas Department of Health and Environment (KDHE) developed
