Rapid purification of the peptide toxins microcystin-LR and nodularin [PDF]
FEMS Microbiology Letters, 1990 An isolation procedure was developed to provide within one day microcystin-LR, a cyclic heptapeptide toxin from Microcystis aeruginosa PCC 7806. After ODS (octadecylsilyl) solid phase extraction, the crude toxin fraction was chromatographed using a strong anion exchange column. The toxin was eluted with 0.02 M ammonium bicarbonate.

Ecohydrology, Volume 19, Issue 1, January‐February 2026.ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

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 ...

Transfer of nodularin to copepod Eurytemora affinis through the microbial food web
, 2009 Nodularia spumigena Mertens ex Bornet & Flahault 1886 (Cyanophyceae) frequently forms harmful blooms in the Baltic Sea, and the toxin nodularin has been found in calanoid copepods during the blooms. Although nodularin has been found at higher trophic

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.

Removal of Microcystins and Nodularin-R from Water by Corncobs Studied Using LC-MS
, 2022 Microcystins (MCs) and nodularins are released during harmful algal blooms (HABs) in fresh and brackish water. Consumption of water contaminated with MCs or nodularins can promote health risks for humans and animals. In this study, The Andersons corncobs

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.

Degradation of the cyanobacterial hepatotoxin, nodularin, under light and dark conditions [PDF]
FEMS Microbiology Letters, 1997 The stability of the cyanobacterial hepatotoxin, nodularin, was determined during the incubation of purified toxin, and in nodularin-containing cell-free extracts and whole filaments of the nodularin-producer, Nodularia spumigena in sunlight and darkness.

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.
