Retracing cyanobacteria blooms in the Baltic Sea
Scientific Reports, 2022 In late summer, massive blooms and surface scums of cyanobacteria emerge regularly in the Baltic Sea. The bacteria can produce toxins and add bioavailable nitrogen fixed from atmospheric nitrogen to an already over-fertilized system.

Comparative metagenomics of toxic freshwater cyanobacteria bloom communities on two continents. [PDF]
PLoS ONE, 2012 Toxic cyanobacterial blooms have persisted in freshwater systems around the world for centuries and appear to be globally increasing in frequency and severity.

ToxinsCyanobacterial blooms are increasingly becoming more intense and frequent, posing a public health threat globally. Drinking water treatment plants that rely on algal bloom-affected waters may create waste (water treatment residuals, WTRs) that ...

Physiology, Blooms and Prediction of Planktonic Cyanobacteria
, 2012 This chapter addresses some of the challenges associated with trying to model population fluctuations, bloom formation and collapse of planktonic cyanobacteria. It is argued that improved modelling and prediction rely on a better understanding of the physiological responses of cyanobacteria to the physical and chemical characteristics of their ...

Control of algal growth in reservoirs with ultrasound [PDF]
, 2009 Algal blooms are a major worldwide water treatment concern due to their potentially harmful effects on humans and livestock. The main cause of algal bloom proliferation is eutrophication of water sources. Anthropogenic effects contribute significantly to

Cyanobacteria bloom: selective filter for zooplankton? [PDF]
Brazilian Journal of Biology, 2015 The Ibirité reservoir is an urban and eutrophic environment, with regular occurrences of cyanobacteria blooms. The reservoir is warm monomict and remains stratified most of the year, circulating in the dry season (winter).

Blooms of Cyanobacteria on the Potomac River [PDF]
Plant Physiology, 1986 Blooms of cyanobacteria have appeared on the Potomac River near Washington, DC in years of drought and low river volume. The location of the bloom may be related to tidal activity. In 1983, the bloom of Microcystis aeruginosa used ammonia as its nitrogen source and contained low levels of toxic peptides.

Cyanobacteria blooms produce teratogenic retinoic acids [PDF]
Proceedings of the National Academy of Sciences, 2012 Deformed amphibians have been observed in eutrophic habitats, and some clues point to the retinoic acids (RAs) or RA mimics. However, RAs are generally thought of as vertebrate-specific hormones, and there was no evidence that RAs exist in cyanobacteria or algae blooms.
