The effect of toxic Microcystis aeruginosa on four different populations of Daphnia [PDF]

, 2002
Cyanobacteria reduce the fitness of many Daphnia species, and blooms in eutrophic lakes may place strong selective pressure upon these primary consumers.

Phytoplankton Under Pressure: Temperature, Precipitation and Cyanobacterial Blooms as Drivers of Chytrid Infections

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Chytrid parasites of phytoplankton infect a wide range of species, including green algae, diatoms, and cyanobacteria. Infection patterns varied, indicating that chytrid occurrence is highly dynamic in space and time. Warmer temperatures, increased rainfall and cyanobacterial bloom events coincided with enhanced infection prevalence on green algae ...

Combined Impact of Nanoplastics and Temperature on Green Algae: Implications for Growth, Lipid Content and Organic Exudates

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
The combined effects of nanoplastics and temperature on green algae were investigated. Higher NP concentration suppressed the temperature‐induced growth of the algae. Temperature plays a dominant role in influencing fatty acid composition and chemistry of AOM than exposure to NPs.

Response of Daphnia's antioxidant system to spatial heterogeneity in Cyanobacteria concentrations in a lowland reservoir. [PDF]

PLoS ONE, 2014
Many species and clones of Daphnia inhabit ecosystems with permanent algal blooms, and they can develop tolerance to cyanobacterial toxins. In the current study, we examined the spatial differences in the response of Daphnia longispina to the toxic ...

Nutrient‐driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria)

Journal of Phycology, Volume 61, Issue 6, Page 1738-1752, December 2025.
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.

Changes in the algal composition, bacterial metabolic activity and element content of biofilms developed on artificial substrata in the early phase of colonization [PDF]

, 2007
Changes in the algal composition and metabolic profiles of bacterial communities as well as the inorganic components were studied on artificial substrata during the early phase of biofilm formation under laboratory conditions in September 2002 and 2003 ...

Antioxidant enzyme activities of Microcystis aeruginosa in response to nonylphenols and degradation of nonylphenols by M-aeruginosa [PDF]

, 2007
The aim of this study was to examine the effects of chemical nonylphenols (NPs) on the antioxidant system of Microcystis aeruginosa strains. The degradation and sorption of NPs by M. aeruginosa were also evaluated.

Development of Chitosan/PVA Nanofibrous Membranes for Efficient Removal of Microcystis aeruginosa

Journal of Applied Polymer Science, Volume 142, Issue 44, November 20, 2025.
Removal of Microcystis aeruginosa from CS/PVA fibers by A‐HSBS. ABSTRACT In this study, chitosan/poly(vinyl alcohol) (CS/PVA) polymeric nanofibers were produced using the Air‐Heated Solution Blow Spinning (A‐HSBS) method and applied for the efficient removal of Microcystis aeruginosa from contaminated water.

Competitive dominance of Microcystis aeruginosa against Raphidiopsis raciborskii is strain- and temperature-dependent

Knowledge and Management of Aquatic Ecosystems, 2020
Microcystis aeruginosa and Raphidiopsis raciborskii (previously Cylindrospermopsis raciborskii) are both common bloom-forming cyanobacteria which can coexist but alternatively dominate in freshwater ecosystems. To predict their blooming dynamics, we need

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

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