%X To prevent water bloom, a new method of inhibiting cyanobacteria's growth was presented based on the bio-effect of ultrasound. The key components of antenna complexes, such as phycobilisome and chlorophyll, are damaged or biosynthetically inhibited by low-power and high-frequency (1.7 MHz) ultrasound efficiently and energy-savingly, so the photosynthesis is restrained and cyanobacteria's growth is inhibited. In the experiments with Spirulina platensis, after the most economic and effective ultrasonic irradiation of 5 min, the concentration was decreased obviously and the rate of growth was slowed down greatly. It was found that phycocyanin was damaged intensely in the experiments, i.e., a selective damage of high-frequency ultrasound on different cell components was found. The explanation was presented based on the quantum effect of high-frequency ultrasound.
