Description
Irem Soyler and co-authors report a 2026 study on how high-frequency sound waves kill a common food-poisoning bacterium, E. coli, and how the bacteria fight back. At low power the killing mechanism was unclear. The team tested whether damage came from reactive chemical species or from physical force.
One sound frequency produced more reactive species inside the bacteria and more membrane damage than another. Adding a green-tea compound greatly boosted the killing effect and damaged the cell surface further. Bacteria pre-treated with sound became weaker against later heat and chemical attack. Mutant tests showed one defence system, tied to a protective chemical inside the cell, was especially important for survival.
