1. Microcystin-XR degradation by bacteria isolated from public water supply system / Degradação da microcistina-XR por bactérias isoladas de sistema de abastecimento público de água
Microcystins are potent hepatotoxins and tumor promoters found in freshwaters that cause public health risks and thus represent a serious problem for water treatment plants. The cyanobacterium genus Microcystis is the most known toxin-producer and the most common bloom-forming in water reservoirs used for public supply. However, some bacteria are able to use

2. Removal of microcystins in water from eutrophic reservoir involving technical of clarification, pre-oxidation with potassium permanangate, adsorption with powdered activated carbon and post-chlorination / Remoção de microcistina em águas provenientes de reservatório eutrofizado associando técnicas de clarificação, pré-oxidação com permanganato de potássio, adsorção em carvão ativado e pós-cloração
The present work had as objective to evaluate the removal of three different concentrations of extracellular microcystins in different combinations of water treatment for supplying, in bench scale, that had as basic sequence the clarification associated or not with the processes of pre-oxidation with KMNO IND.4, adsorption on PAC and post-chlorination. The r

3. Removal of cyanobacteria toxins from drinking water by adsorption on activated carbon fibers
Natural fibers from macadamia nut shell, dried coconut shell endocarp, unripe coconut mesocarp, sugarcane bagasse and pine wood residue were used to prepare activated carbon fibers (ACF) with potential application for removing microcystins. The ACF from pine wood and sugar cane bagasse were used to remove [D-Leucine¹]MCYST-LR from water. After 10 minutes of

4. Microcystis aeruginosa and microcystins removal by dissolved air flotation bench scale study using aluminum sulfate and ferric chloride as coagulants. / Remoção de Microcystis aeruginosa e microsistinas por flotação por ar dissolvido : estudo em escala de bancada utilizando sulfato de alumínio e cloreto férrico como coagulantes
A ocorrência de florações de cianobactérias é preocupante e tem se tornado mais freqüente em mananciais de abastecimento brasileiros. Espécies de cianobactérias tóxicas podem liberar toxinas para a água, oferecendo risco potencial para o homem e animais que tenham contato ou consumam essa água, podendo até levar à morte. Existem alguns estudos q
