Capacity of the silver-doped TiO_2 under UV-C light to restrain cyanobacterial growth was explored with Anabaena sp.PCC 7120 and Microcystis aeruginosa as test species.The survival,chlorophyll bleaching,photosynthetic activity,DNA breakages,antioxidant enzyme activities, lipid peroxidation,and cellular morphologic structure of test cyanobacteria were analyzed.The results indicate that the test cyanobacteria with UV-C photocatalysis by silver-doped TiO_2 sufferd from effects of reactive oxygen species,which promote the damage of the cell wall and the peroxidation of cell membranes,and subsequently,aggravate the losses of cell organelle and viability.The results suggest that UV-C photocatalysis by the silver ions doped TiO_2 could be a promising method to prevent fast and excessive growth of cyanobacteria in eutrophic water sources.
