| Outline of Final Research Achievements |
Due to the increased use of antibiotics, drug-resistant strains have appeared that are resistant to the antibiotic vancomycin, and this resistance has become a major problem. While drug-resistant bacteria can be inactivated through disinfection with chlorine, which is the method used in sewage treatment plants in Japan, this method may not be sufficient to inactivate the genes of these bacteria. In the present study, impulse voltages were applied to drug-resistant bacteria in order to inactivate the bacteria. The results show that inactivation is possible with longer application times of applied voltages above a fixed value.

| Academic Significance and Societal Importance of the Research Achievements |
本成果による微生物の不活性化技術を確立することで，微生物に加え遺伝子損傷による不活性化まで可能となり，耐性遺伝子水平伝搬による新たな水環境での薬剤耐性菌の発生を抑制することができる．また，UVやオゾン殺菌に代わる低コストかつ維持管理が容易な水滅菌技術を導入可能であることが挙げられる．
