“…First, UV radiation alone has an impact on the physiological properties of algal cells . Several studies have demonstrated that UV radiation induces oxidative stress in cyanobacteria, leading to chemical modifications in their DNA and affecting their physiological activities. , Moreover, UV radiation has been shown to increase the specific gravity of algal cells and deactivate the algae. ,, In addition, AA also demonstrated an algicidal effect for freshwater cyanobacteria. − AA inhibits cyanobacterial growth through a nonoxidative pathway by targeting nonheme iron in Photosystem II (PSII) and the iron–sulfur clusters in ferredoxin, selectively interfering with the photosynthetic electron transport chain in algal cells . Considering the effects of UV irradiation and AA molecules on the physiological activity of algal cells and the ability of the UV/AA system to degrade algae-related organic matter, a comprehensive investigation is warranted to understand the efficiency of UV-induced TXC coagulation (UV + TXC) in algae-laden water and the underlying enhanced mechanisms.…”
