Detection and Occurrence of Microcystins and Nodularins in Lake Manatee and Lake Washington-Two Floridian Drinking Water Systems

Frontiers in Water, 2022
Clean, fresh, and safe drinking water is essential to human health and well-being. Occasionally, biological contaminants taint surface water quality used for human consumption and recreation.

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

Functional Ecology, Volume 40, Issue 8, Page 2475-2489, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

Diversity of toxin and non-toxin containing cyanobacterial mats of meltwater ponds on the Antarctic Peninsula: a pyrosequencing approach [PDF]

, 2014
Despite their pivotal role as primary producers, there is little information as to the diversity and physiology of cyanobacteria in the meltwater ecosystems of polar regions.

Cyanotoxin Screening in BACA Culture Collection: Identification of New Cylindrospermopsin Producing Cyanobacteria

, 2021
Microcystins (MCs), Saxitoxins (STXs), and Cylindrospermopsins (CYNs) are some of the more well-known cyanotoxins. Taking into consideration the impacts of cyanotoxins, many studies have focused on the identification of unknown cyanotoxin(s)-producing ...

Nitrogen and Phosphorus Controls on Phytoplankton Growth and Bacterioplankton Communities in Wetland Impoundments

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Nutrient enrichment in shallow lakes and ponds can shift systems from clear water, macrophyte dominance to turbid, phytoplankton dominance. Because the identity and threshold of the limiting nutrients vary among sites, system‐specific evidence is needed to guide water quality management. We conducted 3‐day in situ nutrient‐enrichment bioassays

Bioaccumulation, Distribution and Biotransformation of Cylindrospermopsin in Potato (Solanum tuberosum) After Exposure by Surface or Sprinkler Irrigation

Toxins
Cylindrospermopsin is an emerging cyanotoxin that can lead to phytotoxicity through different mechanisms. The presence of CYN in irrigation waters is of concern due to potential accumulation in plants, increasing the risk of human exposure by the ...

Effects of Modification of Light Parameters on the Production of Cryptophycin, Cyanotoxin with Potent Anticancer Activity, in Nostoc sp.

Toxins, 2020
Cryptophycin-1 is a cyanotoxin produced by filamentous cyanobacteria. It has been evaluated as an anticancer agent with great potential. However, its synthesis provides insufficient yield for industrial use.

A Review of Common Cyanotoxins and Their Effects on Fish

Toxics, 2023
Global warming and human-induced eutrophication drive the occurrence of various cyanotoxins in aquatic environments. These metabolites reveal diversified mechanisms of action, encompassing cyto-, neuro-, hepato-, nephro-, and neurotoxicity, and pose a threat to aquatic biota and human health.

Recent Advances in the Use of Natural Deep Eutectic Solvents for Natural Product Sample Preparation: Focus on Purification, Characterization, and Sustainability

Journal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT This review examines recent advances in the use of natural deep eutectic solvents (NaDES) for natural product sample preparation, with emphasis on extraction, purification, analytical compatibility, and sustainability. NaDES emerge as versatile, tunable, and biocompatible media that enhance the recovery and stability of diverse phytochemicals ...
