Potential use of flow cytometry in toxicity studies with microalgae - Franqueira López, María Dolores; Orosa, Miguel; Torres Vaamonde, José Enrique; Herrero López, Concepción; Cid Blanco, Ángeles
Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by
environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture medium
of two microalgae was analysed by flow cytometry. Parameters assayed were: cell volume, chlorophyll a fluorescence
and cell viability. The variety of results obtained in the present study reveals that flow cytometry is a useful tool in
the toxicity tests with microalgae, both marine and freshwater species, and for different kind of pollutants.
