Inactivation and mechanism of UV222 radiation on cyanobacteria: Microcystis aeruginosa in aggregates and unicellular forms

Puntos clave

• UV222 radiation effectively inactivates cyanobacteria, particularly Microcystis aeruginosa, in both aggregate and unicellular forms.
• Specifically, the inactivation rates for aggregated forms were significantly higher compared to unicellular forms, highlighting structural impacts.
• Analysis of the mechanisms involved in UV222 radiation suggests various pathways contributing to the inactivation process in cyanobacteria.
• Findings indicate that using UV222 radiation could be a viable method for managing harmful algal blooms, requiring further exploration in larger ecosystems.
