Bacteria homologus to Aeromonas capable of microcystin degradation [PDF]

, 2014
Water blooms dominated by cyanobacteria are capable of producing hepatotoxins known as microcystins. These toxins are dangerous to people and to the environment. Therefore, for a better understanding of the biological termination of this increasingly

Absence of Cyanotoxins in Llayta, Edible Nostocaceae Colonies from the Andes Highlands

Toxins, 2020
Edible Llayta are cyanobacterial colonies consumed in the Andes highlands. Llayta and four isolated cyanobacteria strains were tested for cyanotoxins (microcystin, nodularin, cylindrospermopsin, saxitoxin and β-N-methylamino-L-alanine—BMAA) using ...

Planktothrix rubescens Mass Development Reduces Phosphorus Sedimentation: Implications for Lake Nutrient Cycling

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Planktothrix rubescens is a toxin‐producing filamentous cyanobacterium commonly found in temperate stratified lakes. Planktothrix rubescens regulates its buoyancy through intracellular gas vesicles and typically accumulates in the metalimnion during summer stratification, forming substantial biomass within a thin layer.

The accumulation of the cyanobacterial toxin, microcystin, in cherry tomato (Solanum lycopersicum) and bush bean (Phaseolus vulgaris) plants [PDF]

, 2013
We aimed to develop a high-sensitivity method to detect microcystin toxins in fruit tissue and to determine if irrigation with water containing toxic cyanobacteria may result in accumulation of microcystin toxins in fruit tissue and affect fruit ...

Cyanobacteria as multifunctional bioinputs for sustainable intensification, soil health enhancement, and climate resilience in rice‐based cropping systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Ensuring food security goals through the provision of sustainable energy and food without compromising environmental sustainability is the current requirement amid threats from climate change, uncontrolled global population, and scarcity of natural resources.

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Filtering efficiency and feeding mechanisms of Daphnia pulex on Microcystis aeruginosa and Nannochloropsis [PDF]

, 2012
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria ...

Glycogen synthase kinases 3α and 3β in cardiac myocytes: regulation and consequences of their inhibition [PDF]

, 2008
Inhibition of glycogen synthase kinase 3β (GSK3β) as a consequence of its phosphorylation by protein kinase B/Akt (PKB/Akt) has been implicated in cardiac myocyte hypertrophy in response to endothelin-1 or phenylephrine.

Microcystins with Modified Adda⁵-Residues from a Heterologous Microcystin Expression System

ACS Omega
Microcystins are hepatotoxic cyclic heptapeptides produced by some cyanobacterial species and usually contain the unusual β-amino acid 3S-amino-9S-methoxy-2S,6,8S-trimethyl-10-phenyl-4E,6E-decadienoic acid (Adda) at position-5. The full microcystin gene cluster from Microcystis aeruginosa PCC 7806 has been expressed in Escherichia coli.
