Environmentally Friendly and Cost-Effective Approaches to Reduce Toxin Content in Toxic Cyanobacterial Biomasses

Biomass
Cyanobacterial outgrowths are naturally occurring processes in eutrophic aquatic ecosystems. Furthermore, as a result of climate change and anthropogenic pollution, cyanobacteria harmful algal blooms (CyanoHABs) are expanding worldwide.

Interactive effects of stoichiometry and environmental variability regulate cyanobacteria toxicity in two eutrophic bays

Limnology and Oceanography, Volume 70, Issue 11, Page 3506-3519, November 2025.
Abstract Cyanobacteria blooms are a leading threat to water quality globally. Despite this, the timing and frequency of toxin production associated with harmful blooms are not well understood. Here we explore cyanobacteria bloom dynamics and cyanotoxin production in two heavily instrumented shallow, eutrophic bays of Lake Champlain through the lens of ...

Cylindrospermopsin, a cyanobacterial alkaloid: Evaluation of its toxicological activity.

, 2000
This paper describes the natural occurrence of the toxin, cylindrospermopsin, in two species of cyanobacteria found in Australia. The structure and chemical properties of this compound are described along with a nontoxic analog of cylindrospermopsin. The

Photocatalytic degradation of the cyanotoxin cylindrospermopsin, using titanium dioxide and UV irradiation

, 2000
Cylindrospermopsis raciborskii produces the cyanotoxin cylindrospermopsin, which is commonly found in SouthEast Queensland water reservoirs, and has been responsible for the closure of these reservoirs as a source of drinking water in recent times. Thus,

The toxic effects of meta‐tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria

The FEBS Journal, Volume 292, Issue 20, Page 5439-5456, October 2025.
This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...

Cylindrospermopsin adsorption onto activated carbons synthesized from coconut shell: Effect of surface chemical composition on removal efficiency

Adsorption Science & Technology
Cylindrospermopsin (CYN) is a toxic metabolite globally documented in aquatic environments, including human supply water sources. Adsorption onto activated carbon (AC) has emerged as a promising and cost-effective advanced technique to remove this ...

Effects of the cyanobacteria Microcystis aeruginosa on eastern oyster feeding

Ecosphere, Volume 16, Issue 9, September 2025.
Abstract The eastern oyster, Crassostrea virginica, is an estuarine consumer of considerable ecological and economic value, with the ability to selectively feed from a mixed phytoplankton community. Estuarine phytoplankton communities are experiencing an increased presence of small, nutritionally poor, salt‐tolerant, and potentially toxic cyanobacteria,

Recent occurrence of Cylindrospermopsis raciborskii, in Waikato lakes of New Zealand. [PDF]

, 2003
Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth ≤5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand.

Stereoselective Total Syntheses and Reassignment of Stereochemistry of the Freshwater Cyanobacterial Hepatotoxins Cylindrospermopsin and 7-Epicylindrospermopsin

, 2016
A stereoselective total synthesis of the structure 1 proposed for the freshwater cyanobacterial heptatotoxin cylindrospermopsin has been accomplished in approximately 30 operations starting from commercially available 4-methoxypyridine.

A Systematic Literature Review for Evidence of Aphanizomenon flos-aquae Toxigenicity in Recreational Waters and Toxicity of Dietary Supplements: 2000–2017

Toxins, 2018
Previous studies of recreational waters and blue-green algae supplements (BGAS) demonstrated co-occurrence of Aphanizomenon flos-aquae (AFA) and cyanotoxins, presenting exposure risk.
