How does an ultrasonic alga control work?

Collapse of gas vesicles Blue-green algae are capable of travelling through the water column vertically due to their possession of gas vesicles. The ultrasound from the LG Sonic ruptures these vesicles, preventing the algae from rising to the surface and absorbing light for their photosynthesis. Creating a sound barrier Ultrasound from the right frequencies creates a sound barrier in the top layer of the water, reflecting on objects with a different density than water. This affects the buoyancy of many types of algae and prevents algae from floating up to the surface, thus dying by lack of light. Damage of tonoplast As an effect of ultrasound, the tonoplast of green algae can rupture, releasing the contents of the vacuole to the inner cell. Besides this, the adhesion of the cell membrane and the cell wall can be damaged. Prevent bacterial adherence In an unstable environment bacteria adhere to a surface, creating a biofilm. LG Sonic devices create a pressure area around a surface,
