Resumo: | Toxic cyanobacteria and cyanotoxins have been pointed as important players in the control of phytoplankton diversity and species abundance, causing ecological unbalances and contamination of the environment. In vitro experiments have been undertaken to address the impact of toxic cyanobac- teria in green algae. In this regard the aim of this work was to compare the toxicity of two cyanobacteria species, Aphanizomenon ovalisporum and Microcystis aeruginosa, to the green alga Chlorella vulgaris by assessing culture growth when exposed for three and seven days to (I) cyanobacterial cell extracts and (II) pure toxins microcystin-LR (MC-LR) and cylindrospermopsin (CYN). |
