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 ...

Lacustrine Cyanobacteria, Algal Blooms and Cyanotoxins in East Africa: Implications for Human and Ecological Health Protection

Phycology, 2023
Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on the taxonomy, dynamics, toxic effects, human and ecological health ...

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,

Phylogenomic and Pangenomic Assessment of a Mediterranean Strain of Raphidiopsis raciborskii Extends Knowledge of the Global Distribution and Characteristics of a Potentially Toxigenic Cyanobacterium

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
The potentially toxigenic cyanobacterium Raphidiopsis raciborskii has spread to temperate regions and produces massive blooms. This study reports the first taxonomic and functional metagenomic assessment of a strain from the Mediterranean, thus filling a significant gap in global distribution.

Effects of Seasonal Dynamics on Cyanobacteria Proliferation in Aquaculture Fish Ponds

Aquaculture Research, Volume 2025, Issue 1, 2025.
Aquaculture production supports the United Nations Sustainable Development Goals (SDGs), especially SDG 2 (Zero Hunger), by enhancing food security and sustainable practices. This study investigated the seasonal dynamics of cyanobacterial (CB) blooms in aquaculture fishponds in South Africa (SA) and Nigeria (NGA). Water samples were collected twice per

Immunohistochemical approach to study Cylindrospermopsin distribution in tilapia (Oreochromis niloticus) under different exposure conditions [PDF]

, 2014
Cylindrospermopsin (CYN) is a cytotoxic cyanotoxin produced by several species of freshwater cyanobacteria (i.e., Aphanizomenon ovalisporum). CYN is a tricyclic alkaloid combined with a guanidine moiety.

Effects of Harmful Algal Blooms on Amphibians and Reptiles are Under‐Reported and Under‐Represented

Environmental Toxicology and Chemistry, Volume 43, Issue 9, Page 1936-1949, September 2024.
Abstract Harmful algal blooms (HABs) are a persistent and increasing problem globally, yet we still have limited knowledge about how they affect wildlife. Although semi‐aquatic and aquatic amphibians and reptiles have experienced large declines and occupy environments where HABs are increasingly problematic, their vulnerability to HABs remains unclear.

Responsible innovation: Mitigating the food safety aspects of cultured meat production

Journal of Food Science, Volume 89, Issue 8, Page 4638-4659, August 2024.
Abstract There is much interest in cultured (cultivated) meat as a potential solution to concerns over the ecological and environmental footprint of food production, especially from animal‐derived food products. The aim of this critical review is to undertake a structured analysis of existing literature to (i) identify the range of materials that could

The chemical and microbiological safety of emerging alternative protein sources and derived analogues: A review

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Climate change and changing consumer demand are the main factors driving the protein transition. This shift toward more sustainable protein sources as alternatives to animal proteins is also reflected in the rapid upscaling of meat and dairy food analogues.

Successful isolation and cultivation of Cylindrospermopsis raciborskii strains isolated from finished drinking water samples [PDF]

, 2019
This work presents the successful establishment of Cylindrospermosis raciborskii cultures isolated from water samples collected at the exit point of Water Treatment Plant (WTP). An intense bloom dominated by filamentous cyanobacteria (Aphanizomenon spp.,
