Suppression Effects of UV-C Irradiation on Photosynthetic Activities of Microcystis Aeruginosa and the Recovery Patterns
1. Introduction UV-C irradiation is an alternative to prevent cyanobacterial blooms. The growth suppression effects of UV-C irradiation have been verified for several cyanobacterial species. However, the mechanisms of growth suppression on Microcystis aeruginosa under UV-C stress have not been well explained. There is a lack of systematic study to unravel the specific involvement of UV-C irradiation on impairments of algal photosynthetic processes. In the present study, the responses of photosynthetic processes of M. aeruginosa under UV-C stress during the growth suppression period were investigated by measuring changes in pigments concentration, photochemical efficiency, PS II core protein Dl content, and the coding genes expressions by adopting a series of biophysical, biochemical and molecular biological techniques.
