“…An excessive increase in cyanobacterial mass known as the Bbloom of blue-green algae^leads to a disruption of aquatic ecosystems owing to the production of cyanobacterial toxins (including hepatotoxins, neurotoxins, cytotoxins, and dermatotoxins), consumption of large amounts of oxygen during cell decomposition, growth of primary production, reduction of water clarity, deterioration of organoleptic parameters, and the consequent decrease in biodiversity [5,6]. Therefore, improving our understanding of the impact of the environment on the development and activity of cyanobacteria is necessary to enable the use of its natural potential, in particular, biological control agents such as bacteria, viruses, and protozoa [7][8][9] to limit the associated threat.…”

Cyanophages Infection of Microcystis Bloom in Lowland Dam Reservoir of Sulejów, Poland

et al. 2015

An increased incidence of cyanobacterial blooms, which are largely composed of toxigenic cyanobacteria from the Microcystis genus, leads to a disruption of aquatic ecosystems worldwide. Therefore, a better understanding of the impact of environmental parameters on the development and collapse of blooms is important. The objectives of the present study were as follows: (1) to investigate the presence and identity of Microcystis-specific cyanophages capable of cyanobacterial cell lysis in a lowland dam reservoir in Central Europe; (2) to investigate Microcystis sensitivity to phage infections with regard to toxic genotypes; and (3) to identify key abiotic parameters influencing phage infections during the summer seasons between 2009 and 2013. Sequencing analysis of selected g91 gene amplification products confirmed that the identified cyanophages belonged to the family Myoviridae (95 % homology). Cyanophages and Microcystis hosts, including toxic genotypes, were positively correlated in 4 of the 5 years analyzed (r = 0.67-0.82). The average percentage of infected Microcystis cells varied between 0.1 and 32 %, and no particular sensitivity of the phages to toxigenic genotypes was recorded. The highest number of cyanophages (>10(4) gene copy number per microliter) was observed in the period preceded by the following: an increase of the water retention time, growth of the water temperature, optimum nutrient concentrations, and the predomination of Microcystis bloom.

Effects of Biological Control Agents on Nuisance Cyanobacterial and Diatom Blooms in Freshwater Systems

et al. 2007

View full text Add to dashboard Cite

Biological control agents such as bacteria and ciliates were tested alone and in combination for their abilities to decrease densities of the warm-weather cyanobacterium, Microcystis aeruginosa, and the cold-weather centric diatom, Stephanodiscus hantzschii. The growth of Microcystis aeruginosa was effectively suppressed by the algicidal bacterium, Streptomyces neyagawensis, and the predator heterotrich ciliate, Stentor roeselii. However, co-treatment increased the algal density rather than decreasing it, suggesting that Streptomyces neyagawensis and Stentor roeselii have an antagonistic relationship. Additional experiments revealed that the density of Stephanodiscus hantzschii was effectively reduced by the bacterium, Pseudomonas putida, and by the abovementioned strain of Stentor roeselii. Co-treatment had a greater antialgal effect than treatment with either bio-agent alone, indicating that the two act synergistically. These results suggest the potential antialgal efficacy of treatments with multiple biological control agents, providing new insight that may be useful for the bioremediation of nuisance algal blooms in freshwater.

“…Eles são também utilizados como organismos-teste em experimentos de toxicidade (Twagilimana et al 1998, Nalecz-Jawecki 2004 devido a sua sensibilidade a alterações ambientais, ao seu curto ciclo de vida e a sua facilidade de cultivo e manutenção. Os protozoários estão também sendo investigados quanto à possibilidade de utilização em controle biológico de florações de algas e de cianobactérias (Sigee et al 1999) e na produção de metabólitos bioativos (Guella et al 1994). …”

Checklist dos "protozoários" de água doce do Estado de São Paulo, Brasil

Species checklists are important to know the local biodiversity, its ecology and scale its biotechnological and economic exploration and conservation. In this work the protozoan data (ciliates, naked amoebas, tecamoebas, heliozoans and heterotrophic flagellates) from São Paulo State have been listed. From 75 environments analized to this moment, 471 different protozoan taxa were recorded, distributed in 218 genera and 304 species. From the protozoan groups analyzed, the most representative was the ciliate with 160 genera and 219 species. Among the ciliates, two were new records: Neobursaridium gigas Balech, 1941
