Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

open access: yesEcohydrology, 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

Taxonomic diversity and toxicological assessment of Cyanobacteria in Moroccan inland waters [PDF]

open access: yes, 2009
Research on the ecology, biodiversity and toxicology of cyanobacteria in Moroccan inland waters has been carried out since 1994. The results demonstrate the existence of several taxa of cyanobacteria. Most of them are toxic, bloom‑forming species present

A choanoflagellate (craspedomonad) epiphytic on Microcystis aeruginosa

open access: yesSouth African Journal of Botany, 1987
A. large population of the choanoflagellate, Salpingoeca sp., developed on Microcystis aeruginosa Kütz. emend. Elenkin which had been collected from a hypertrophic lake and maintained for several days in the laboratory. The choanoflagellate appears to be related to, but not identical to, S.

Occurrence and Distribution of Cyanobacteria and their Toxins in Silver Lake, New Hampshire [PDF]

open access: yes, 2008
A study of Silver Lake, NH was performed as part of a 5-lake assessment of cyanobacteria prevalence and distribution. Multi-parameter fluorescence probe measurements of chlorophyll a and cyanobacteria concentrations (PC, phycocyanin fluorescence) were ...

Hydrogen peroxide induces apoptotic-like cell death in Microcystis aeruginosa (Chroococcales, Cyanobacteria) in a dose-dependent manner [PDF]

open access: yes, 2012
We investigated the capability of Microcystis aeruginosa to cause apoptosis by pursuing morphological, molecular and physiological characteristics after exposure to H2O2.

Extracellular polysaccharide synthesis in a bloom-forming strain of Microcystis aeruginosa: implications for colonization and buoyancy

open access: yesScientific Reports, 2019
Microcystis, the dominant species among cyanobacterial blooms, normally forms colonies under natural conditions but exists as single cells or paired cells in axenic laboratory cultures after long-term cultivation.

Nitrous oxide (N 2 O) synthesis by Microcystis aeruginosa

open access: yes, 2022
Abstract. Pure cultures of Microcystis aeruginosa synthesized nitrous oxide (N2O) when supplied with nitrite (NO2-) in darkness (198.9 nmol·g-DW-1·h-1 after 24 hours) and illumination (163.1 nmol∙g-DW-1∙h-1 after 24 hours) whereas N2O production was negligible in abiotic controls supplied with NO2- and in cultures deprived of exogenous nitrogen.

Effects of iron on growth, pigment content, photosystem II efficiency, and siderophores production of Microcystis aeruginosa and Microcystis wesenbergii [PDF]

open access: yes, 2007
Changes in growth, photosynthetic pigments, and photosystem II (PS II) photochemical efficiency as well as production of siderophores of Microcystis aeruginosa and Microcystis wesenbergii were determined in this experiment.

Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands

open access: yesToxins, 2013
In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g−1 dry-weight microcystin, the vomit of one of ...
