Cyanopeptide profiles before and after exposure to simulated sunlight (pH 9.3; DOM 5.5 mgC L−1) in relative abundance (%) for a Microcystis aeruginosa PCC7806; b Dolichospermum flos aquae; c Microcystis aeruginosa UV006; d Planktothrix rubescens. The hashed portion of the bars represents the percentage removal of each cyanopeptide after 3 h exposure to simulated sunlight. The total percentage removal of the whole cyanopeptide pool for each specie is represented by the bar at the top of each chart (dark blue). Only cyanopeptides that contributed with more than 1% to the total cyanopeptide pool are represented here. Compound names indicated as “group” refer to structural isomers detailed in Table S5 and for the compounds marked with an asterisk (Microcystin-(H4)YR-Group-1035, Microcyclamide 7806B, Aerucyclamide B, Aerucyclamide C) the degradation could not be followed in the presented experiment
