Incorporation of diazotrophically fixed nitrogen by juvenile fish in a coastal sea

Limnology and Oceanography, Volume 70, Issue 10, Page 2968-2981, October 2025.
Abstract Nitrogen‐fixing cyanobacterial blooms worldwide have been shown to support production in primary consumers such as zooplankton and benthic invertebrates, but there have been few estimates of how much of the cyanobacterial nitrogen ends up in secondary consumers, such as fish.

LC-MS/MS Validation and Quantification of Cyanotoxins in Algal Food Supplements from the Belgium Market and Their Molecular Origins

Toxins, 2022
Food supplements are gaining popularity worldwide. However, harmful natural compounds can contaminate these products. In the case of algae-based products, the presence of toxin-producing cyanobacteria may cause health risks.

Assessing the Impacts of Land‐Use Change and Climate Variability on Cyanobacterial Abundance and Toxicity in Shallow Lakes

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT The global increase in the frequency and intensity of cyanobacteria blooms has been widely attributed to changes in land‐use practices and climate variability, yet little is known of how toxicity has varied historically relative to cyanobacteria abundance.

Rekombination hybrider Megasynthasen als Schlüssel für die Evolution metabolischer Diversität in Cyanobakterien

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Natürliche Kombinatorik: Die evolutionäre Rekombination und Anpassung von drei cyanobakteriellen Biosynthese‐Genclustern führte zur Entstehung von Minutumamiden, einer neuen Familie von Peptid‐Polyketid‐Hybriden. Mittels retro‐evolutionärer Analyse gelang die Entdeckung des Nostopeptolids KVJ3, einem evolutionären Vorfahren, der die Biosynthese von ...

Multimedia distributions, bioaccumulation, and trophic transfer of microcystins in the Geum River Estuary, Korea: Application of compound-specific isotope analysis of amino acids [PDF]

, 2019
To determine distributions, bioaccumulation, and trophic transfer of freshwater cyanobacterial toxins such as microcystins (MCs), surface water, suspended solids, sediments, and coastal organisms were collected from seven stations in inner and outer ...

Mixing and Matching of Hybrid Megasynthases is a Hub for the Evolution of Metabolic Diversity in Cyanobacteria

Angewandte Chemie International Edition, Volume 64, Issue 26, June 24, 2025.
Natural combinatorics: Evolutionary mixing and matching of three cyanobacterial biosynthetic gene clusters resulted in the emergence of minutumamides, a novel family of peptide‐polyketide hybrids. Retro‐evolutionary analysis led to the discovery of nostopeptolide KVJ3, an evolutionary ancestor that links nostopeptolide and minutumamide biosynthesis and

Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS

Chemosensors, 2023
Dairy milk holds a prominent position as a widely consumed food, particularly among infants and children. However, it is crucial to address the presence of multiple natural toxic compounds that may co-occur in dairy milk to ensure its safety prior to ...

CYANO RT-Microarray: A Novel Tool to Detect Gene Expression in Cyanobacteria [PDF]

, 2018
EU μAQUA made early warning systems for freshwater pathogens and toxins. Barcodes for each cyanobacterial toxin gene published before 2011 were designed and used in a microarray format to capture messenger RNA to detect toxin gene expression at early ...

The Great Lakes Winter Grab: Limnological data from a multi‐institutional winter sampling campaign on the Laurentian Great Lakes

Limnology and Oceanography Letters, Volume 10, Issue 1, Page 37-61, February 2025.
Abstract Interest in winter limnology is growing rapidly, but progress is hindered by a shortage of standardized multivariate datasets on winter conditions. Addressing the winter data gap will enhance our understanding of winter ecosystem function and of lake response to environmental change.
