Hydrogen peroxide treatment promotes chlorophytes over toxic cyanobacteria in a hyper-eutrophic aquaculture pond.
TLDR
It is demonstrated that H2O2 can be an effective, rapid algaecide for controlling toxigenic cyanobacteria when properly dosed and showed the greatest negative effect on zooplankton. Expand
Prevalence of paralytic shellfish poison-producing Planktothrix agardhii and Cylindrospermopsis raciborskii in a Brazilian semi-arid reservoir
TLDR
This is the first report of PSP-producer cyanobacteria species isolated in Northeastern Brazil and the first reported of a P. agardhii synthesizing dcGTX2/3. Expand
Impact of filamentous cyanobacteria on the water quality of two tropical reservoirs
TLDR
The data collected demonstrates that a season with intensive rainfall may lead to lower cyanobacteria concentrations probably due to water dilution and higher flushing rates, and increase in diversity was observed during the intense rainy season of 2011, suggesting a slight improvement of water quality.

Growth of the microalgae Tetraselmis tetrathele and nitrate depletion in culture medium Guillard f/2 and Conway - doi: 10.4025/actascibiolsci.v35i2.13971
TLDR
Results showed that microalgae development caused nutrient depletion, since the authors observed an inversely proportional relationship between nitrate concentration and algal biomass during the cultivation. Expand
Effect of hydrogen peroxide on natural phytoplankton and bacterioplankton in a drinking water reservoir: Mesocosm-scale study.
TLDR
Evaluated the effects of a single H2O2 addition over 120 h in mesocosms introduced in a reservoir presenting a Planktothrix-dominated cyanobacterial bloom to indicate that this approach is efficient in suppressing cyanob bacterial blooms and improving water quality in tropical environments. Expand
Lipid content of marine microalgae Chaetoceros muelleri Lemmermann (Bacillariophyceae) grown at different salinities
TLDR
The present study aimed to evaluate the growth and concentration of total lipids of the microalga C. muelleri Lemmermann cultivated at three different salinities (15, 25 and 35) and showed that the lipid yield showed higher than expected levels. Expand
Environmental factors associated with toxic cyanobacterial blooms across 20 drinking water reservoirs in a semi-arid region of Brazil.
TLDR
Interestingly, specific cyanobacterial taxa were influenced by different biotic and abiotic factors, and nitrogen-to-phosphorus and evaporation were positively related to saxitoxin-producing taxa, especially Raphidiopsis raciborskii, while temperature, electrical conductivity, total phosphorus, and transparency were positively associated with microcystin-producingTaxa. Expand
Icyano: a cyanobacterial bloom vulnerability index for drinking water treatment plants
Managing freshwater systems has become a challenge for global water utilities given that cyanobacterial blooms have been increasing in frequency and intensity. Consequently, a water quality indexExpand
Pond bank access as an approach for managing toxic cyanobacteria in beef cattle pasture drinking water ponds
TLDR
Based on observations made during sampling events and available water quality data, livestock-mediated bioturbation is causing elevated total suspended solids that lead to reduced phytoplankton abundance and microcystin despite high concentrations of nutrients, such as phosphorus and nitrogen.
