Biomonitoring genotoxicity and cytotoxicity of Microcystis aeruginosa (Chroococcales, Cyanobacteria) using the Allium cepa test

► Cyanobacteria have an enormous number of bioactive compounds. ► We analyze the genotoxicity and ecotoxicity from two strains of Microcystis aeruginosa using Allium cepa. ► Allium cepa was found suitable for as a pre-screening technique during cyanobacterial blooms. ► This is important since it is a more economical technique that can be applied in developing nations.
