Abstract

Microalgae applications are becoming more and more diverse, from wastewater treatment to biofuel and plastics production. Another promising and sustainable application is the removal of organic compound from drinking water and wastewater sources. This study focused on the removal of the iodinated contrast media, iohexol by the microalga Chlorella vulgaris. C. vulgaris removed 40–50% of the iohexol from the medium in 27 days, 23–30% of which was biodegraded through two main pathways: oxidation and hydrolysis. Similar transformation pathways, producing the same degradation products, were observed for incubation with microalgae and for ozonation.
