- •
Dissolved organic matter from cyanobacteria exudation and a lake was characterized.
- •
Molecular patterns of dissolved organic matter photodegradation were examined.
- •
Autochthonous and allochthonous signatures were identified in lake water.
- •
Lake water was more photoreactive than cyanobacteria exudates.
- •
Photodegradation increased similarity between lake water and cyanobacteria exudates.
