Is the Cyanobacterial Bloom Composition Shifting Due to Climate Forcing or Nutrient Changes? Example of a Shallow Eutrophic Reservoir

open access: yesToxins, 2021
Cyanobacterial blooms in eutrophic freshwater is a global threat to the functioning of ecosystems, human health and the economy. Parties responsible for the ecosystems and human health increasingly demand reliable predictions of cyanobacterial ...

Phytoplankton Under Pressure: Temperature, Precipitation and Cyanobacterial Blooms as Drivers of Chytrid Infections. [PDF]

open access: yesEnviron Microbiol Rep
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 ...

Comparison of Bacterial Assemblages Associated with Harmful Cyanobacteria under Different Light Conditions

open access: yesMicroorganisms, 2022
Harmful cyanobacterial blooms in freshwater ecosystems are closely associated with changes in the composition of symbiotic microbiomes, water quality, and environmental factors.

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]

open access: yes, 2012
An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

Occurrence of Harmful Algal Blooms in Freshwater Sources of Mindu and Nyumba ya Mungu Dams, Tanzania

open access: yesJournal of Toxicology, 2023
Harmful algal blooms (HABs) pose a significant threat to aquatic ecosystems and human health due to the production of toxins. The identification and quantification of these toxins are crucial for water quality management decisions.

Removal of Microcystis aeruginosa cells using the dead cells of a marine filamentous bacterium, Aureispira sp. CCB-QB1 [PDF]

open access: yesPeerJ, 2022
Inorganic and synthetic flocculants are widely investigated for removing harmful microalgae, such as Microcystis aeruginosa. However, their toxicity and non-biodegradability are shortcomings.

Recreational exposure during algal bloom in carrasco beach, uruguay: A liver failure case report [PDF]

open access: yes, 2017
In January 2015, a 20-month-old child and her family took part in recreational activities at Carrasco and Malvín beaches (Montevideo, Uruguay). An intense harmful algae bloom (HAB) was developing along the coast at that time.

Characterisation of host growth after infection with a broad-range freshwater cyanopodophage [PDF]

open access: yes, 2014
Freshwater cyanophages are poorly characterised in comparison to their marine counterparts, however, the level of genetic diversity that exists in freshwater cyanophage communities is likely to exceed that found in marine environments, due to the habitat
