| Outline of Final Research Achievements |
Bacteria swim to search favorable environments for their survival. If their locomotion apparatus, flagellar motor, is easy to be broken, they cannot live a good life. Therefore the flagellar motor should have sufficient mechanical strength. However, no quantitative data of its strength had been reported. In this study, we developed a method to measure the motor strength, and obtained the quantitative data of motor strengths for Salmonella wild type and mutants whose motors are easy to be broken in viscous environment. Our results indicate that the wild type motor has just enough strength for bacteria to move around their growth environment.
