Procedures of partial purification for phycobiliproteins from cyanobacteria isolated from soils of Republic of Moldova

open access: yesStudia Universitatis Babeș-Bolyai. Biologia, 2018
Investigation of the new cyanobacterial strains, for use as potential sources of bioactive substances, including phycobiliproteins, encounters some difficulties due to presence of toxins (microcystins) produced by some cyanobacterial strains ...

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Toxicity and genotoxicity in Astyanax bimaculatus (Characidae) induced by microcystins from a bloom of Microcystis spp

open access: yesGenetics and Molecular Biology, 2010
Studies of genotoxicity in fish caused by cyanobacterial microcystins can be useful both in determining the sensitivity of native species, as well as comparing exposure routes.

Gastrointestinal toxicity induced by microcystins

open access: yesWorld Journal of Clinical Cases, 2018
Microcystins (MCs) are produced by certain bloom-forming cyanobacteria that can induce toxicity in various organs, including renal toxicity, reproductive toxicity, cardiotoxicity, and immunosuppressive effects. It has been a significant global environmental issue due to its harm to the aquatic environment and human health.

Planktothrix rubescens Mass Development Reduces Phosphorus Sedimentation: Implications for Lake Nutrient Cycling

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Planktothrix rubescens is a toxin‐producing filamentous cyanobacterium commonly found in temperate stratified lakes. Planktothrix rubescens regulates its buoyancy through intracellular gas vesicles and typically accumulates in the metalimnion during summer stratification, forming substantial biomass within a thin layer.

Investigation of Microcystin Processing, Production and Export by Microcystis sp.

open access: yes, 2014
During this study, the effect of different processing methods on the microcystin quota (microcystins per cell) was investigated. Microcystins from two Microcystis strains and one Planktothrix strain were quantified using liquid chromatography-mass ...
