Investigation of the toxicity of cyanobacterial peptides by chemical biology approaches [PDF]

, 2014
Global warming together with the extensive agriculture favours the uncontrolled growth of cyanobacteria, also called blue-green algae. Being one of the oldest life forms on our planet, they have reached evolutionary perfection over time.

Biosensors for Biotoxins Detection and Monitoring

Advanced Sensor Research, Volume 5, Issue 6, June 2026.
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...

Recent advancement of biosensor technology for the detection of microcystin-LR

, 2020
Microcystins are a class of toxins that are mainly produced by cyanobacteria and among them, microcystin-leucine arginine (microcystin-LR) is one of the most toxic and harmful of the fresh water toxins causing many accidents and threats to human health ...

Diversity of microcystin-producing genotypes in Brazilian strains of Microcystis (Cyanobacteria)

Brazilian Journal of Biology
Microcystis Kützing ex Lemmermann is among the genera of cyanobacteria often associated to toxic blooms with the release of microcystins. A gene cluster codes for microcystin synthetases, which are involved in the biosynthesis of this toxin.

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

Gold coated dual-resonance long-period fiber gratings (DR-LPFG) based aptasensor for cyanobacterial toxin detection

Sensing and Bio-Sensing Research, 2019
Here, we present the development of aptasensor for the label-free, stable, and sensitive detection of environmental toxin microcystin-LR (MC-LR). A thiolated aptamer used as a bio-receptor was covalently immobilized on dual-resonance long-period fiber ...

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 ...

Photocatalytic degradation of microcystin-LR in aqueous solutions

Chemosphere, 2013
In this work, the photocatalytic degradation of aqueous microcystin-LR was studied using TiO(2) and ZnO as photocatalysts. The process was optimised and characterised at the bench scale (200 mL); both semiconductors exhibited a high degradation capacity at reaction times of 1 min (degradation greater than 95%).

Influencing factors and health risk assessment of microcystins in the Yongjiang river (China) by Monte Carlo simulation [PDF]

PeerJ, 2018
The Yongjiang river is a large, shallow, hyper-trophic, freshwater river in Guangxi, China. To investigate the presence of microcystin-RR, microcystin-LR, and microcystin-YR (MC-RR, MC-LR, and MC-YR) in the Yongjiang river and describe their correlation ...
