Resumo

Eutrofization of reservoirs supplying drinking water deteriorates water quality, and may affect consumer's health. This is the case of the hepatotoxin microcystin, which is produced by the cyanobacteria Microcystis aeruginosa. Within the framework of Cianoalerta projects we have developed methods for the prompt detection of specific cyanobacteria blooms, a crucial step towards efficient water treatment, thus improving the quality of the product supplied. Seasonal changes in zeaxanthin and beta-carotene paralleled those shown by the cyanobacteria Oscillatoria spp, Anabaena and cocoid forms of cyanobacteria, but were different from those shown by Microcystis. According to our results, these photopigments can be used as indicators of the dynamics of these cyanobacterial populations.
