Cyanopeptide profiles of four cyanobacterial strains, Dolichospermum flos aquae, Mirocystis aeruginosa PCC7806, Microcystis aeruginosa UV006 and Planktothrix rubescens, as a cyanopeptide concentration per dried biomass (µg mg⁻¹ dry wt) and b relative abundance of cyanopeptide classes including aeruginosins (green), anabaenopeptins (blue), cyanopeptolins (orange), cyclamides (purple), microcystins (yellow) and microginins (red). The number of total cyanopeptides produced by each strain is reported to the side of each bar (#)
