In Vitro Toxicological Assessment of Cylindrospermopsin: A Review [PDF]

Toxins, 2017
Cylindrospermopsin (CYN) is a cyanobacterial toxin that is gaining importance, owing to its increasing expansion worldwide and the increased frequency of its blooms. CYN mainly targets the liver, but also involves other organs.

Identification of 7-Deoxy-desulfo-argino-cylindrospermopsin, the Missing Piece in Cylindrospermopsin Biosynthesis

Journal of the American Chemical Society, 2022
Cylindrospermopsin, a major cyanotoxin, is produced by freshwater cyanobacteria. Its biosynthesis starts from arginine and glycine and involves five polyketide synthases and several tailoring enzymes. We report the identification of 7-deoxy-desulfo-argino-cylindrospermopsin in several cylindrospermopsin-producing cyanobacteria using mass spectrometry ...

Characterization of cylindrospermopsin chlorination

Science of The Total Environment, 2010
In temperate countries, the occurrence of cyanobacterial blooms threatens drinking water resources. Consequently, cyanotoxins are increasingly considered in water treatment, and their reactions with chlorine used to disinfect drinking water are particularly investigated.

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States. [PDF]

Glob Chang Biol Commun
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

Evaluation of the Removal and Effects of Cylindrospermopsin on Ripened Slow Sand Filters

Toxins, 2023
The occurrence of toxic blooms of cyanobacteria has been a matter of public health interest due to the cyanotoxins produced by these microorganisms. Cylindrospermopsin (CYN) is a cyanotoxin of particular concern due to its toxic effects on humans.

Limnofasciculus delicatus (Coleofasciculaceae, Coleofasciculales), a Novel Mat-Forming Cyanobacterium From Shenandoah River, Virginia, USA. [PDF]

Environ Microbiol Rep
A novel mat‐forming benthic freshwater cyanobacterium, Limnofasciculus delicatus, is described based on morphological, phylogenetic and genomic evidence from the North and South Forks of the Shenandoah River. Although Limnofasciculus delicatus lacks biosynthetic gene clusters associated with the production of known cyanotoxins, it occurs in association

Dynamics of the Toxin Cylindrospermopsin and the Cyanobacterium Chrysosporum (Aphanizomenon) ovalisporum in a Mediterranean Eutrophic Reservoir

Toxins, 2014
Chrysosporum ovalisporum is a cylindrospermopsin toxin producing cyanobacterium that was reported in several lakes and reservoirs. Its growth dynamics and toxin distribution in field remain largely undocumented.

Immunomodulatory Effects of Cylindrospermopsin in Human T Cells and Monocytes

Toxins, 2023
Cylindrospermopsin (CYN) is a cyanotoxin with an increasing occurrence, and therefore it is important to elucidate its toxicity profile. CYN has been classified as a cytotoxin, although the scientific literature has already revealed that it affects a ...

Recent Advances in Cyanobacterial Cytotoxin Biosensors Focused on Cylindrospermopsin

Chemosensors, 2023
Cylindrospermopsin (CYN) is a freshwater algal toxin produced during the proliferation of harmful cyanobacteria, known as cyanobacterial algal blooms (cyano-HABs). Recently, the effects of global warming have facilitated the growth of cyano-HABs, leading

Multi-Omic Assessment of Microbial Communities and Their Polyketide Biosynthetic Potential Across Abyssal Sediments. [PDF]

Environ Microbiol
Abyssal sediments were assessed for taxonomic diversity and polyketide biosynthetic potential and compared to metagenomic and metabolomic assessments of the same sediments. Biodiversity differences were documented across biogeochemical regimes with the results providing baseline awareness of what might be lost should deep‐sea microbiomes be disrupted ...
