| Outline of Final Research Achievements |
We developed an innovative device capable of trapping oil droplets for the long-term imaging of Alcanivorax borkumensis-mediated oil degradation. Through our research, we determined the physical mechanism underlying this process. In collaboration with theoretical physicists, we constructed a comprehensive theoretical physical model. Furthermore, we meticulously measured the interfacial properties of Alcanivorax borkumensis, providing critical insights into its interactions with oil. Our study also revealed the disruptive effects of chemical dispersants on biofilms. Our findings were published in Science, advancing bioremediation by elucidating bacterial oil degradation mechanisms and the role of dispersants in managing oil spills.
