Novel virulent and temperate cyanophages predicted to infect Microcoleus associated with anatoxin‐producing benthic mats

Environmental Microbiology, Volume 25, Issue 12, Page 3319-3332, December 2023., 2023
We explore the previously undescribed diversity of phages associated with anatoxin‐producing benthic mats from rivers, including a novel virulent cyanophage with a ‘jumbo’ genome. This virulent cyanophage is predicted to infect anatoxin‐producing Microcoleus and its appearance is concomitant with the host decline, supporting the kill‐the‐winner ...

Spatio-temporal variation of cyanobacteria and cyanotoxins in public supply reservoirs of the semi-arid region of Brazil

Journal of Limnology, 2019
Cyanobacteria harmful algal blooms (CyanoHABs) have become increasingly frequent and intense in public supply reservoirs as a result of eutrophication and global climate change.

Cytotoxicity and intestinal permeability of phycotoxins assessed by the human Caco-2 cell model

Ecotoxicology and Environmental Safety, 2023
Phycotoxins are a class of multiple natural metabolites produced by microalgae in marine and freshwater ecosystems that bioaccumulate in food webs, particularly in shellfish, having a great impact on human health.

A Perspective on Removal of Cyanotoxins from Water Through Advanced Oxidation Processes

Global Challenges, Volume 7, Issue 9, September 2023., 2023
Sulfate radical‐based advanced oxidation processes (AOPs) excel in cyanotoxin removal. Their high reactivity efficiently degrades diverse cyanotoxins, ensuring safe water quality. Their versatility and effectiveness make them the most suitable AOPs and safeguard aquatic ecosystems and human health.

Evaluation of environmental factors and microbial community structure in an important drinking-water reservoir across seasons

Frontiers in Microbiology, 2023
The composition of microbial communities varies in water and sediments, and changes in environmental factors have major effects on microbiomes. Here, we characterized variations in microbial communities and physicochemical factors at two sites in a large

Nitrogen Limitation Promotes Accumulation and Suppresses Release of Cylindrospermopsins in Cells of Aphanizomenon Sp.

Toxins, 2014
As the biosynthesis of cylindrospermopsin (CYN) is assumed to depend on nitrogen availability, this study investigated the impact of nitrogen availability on intra- and extracellular CYN and deoxy-CYN (D-CYN) contents in three Aphanizomenon strains from

Spatial and Temporal Variation in Paralytic Shellfish Toxin Production by Benthic Microseira (Lyngbya) wollei in a Freshwater New York Lake

Toxins, 2019
Butterfield Lake is a mesotrophic lake in New York State where residents and pets have experienced unexplained health issues. Microseira wollei (basionym Lyngbya wollei) was found at two of 15 sites in Butterfield Lake and analyzed for microcystins ...

Multiple Stressors at the Land-Sea Interface: Cyanotoxins at the Land-Sea Interface in the Southern California Bight

Toxins, 2017
Blooms of toxic cyanobacteria in freshwater ecosystems have received considerable attention in recent years, but their occurrence and potential importance at the land-sea interface has not been widely recognized.
