Ultrasound-enhanced coagulation for Microcystis aeruginosa removal
Ultrasonics Sonochemistry, 2009 Source water eutrophication has caused serious problems in drinking water supplies, with enhanced coagulation widely used to remove the resulting algae. This paper investigates the use of sonication to improve the removal by coagulation of Microcystis aeruginosa, a common species of toxic algae.

Effect of fluid motion on colony formation in Microcystis aeruginosa
Water Science and Engineering, 2013 Microcystis aeruginosa, generally occurring in large colonies under natural conditions, mainly exists as single cells in laboratory cultures. The mechanisms involved in colony formation in Microcystis aeruginosa and their roles in algal blooms remain ...

Ecotoxicology and Environmental Safety, 2016 Proliferation of cyanobacteria in aquatic ecosystems has caused water security problems throughout the world. Our preliminary study has showed that Pseudomonas aeruginosa can inhibit the growth of cyanobacterium, Microcystis aeruginosa. In order to explore the inhibitory mechanism of P.

Hemagglutinating activity of Microcystis aeruginosa (Cyanobacterium).
NIPPON SUISAN GAKKAISHI, 1987 Natural Microcystis aeruginosa specimens collected mainly from Suwa and Kasumigaura lakes were examined for both the hemagglutinating activity for mammalian erythrocytes and the toxicity in mice. Sixteen out of the 18 samples examined showed a hemagglutinating activity for rabbit erythrocytes, ten for rat and four for mouse erythrocytes. Ten strains in

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