Outline of Final Research Achievements

Humans are living creatures. Bacteria are also living things that feel stress and respond against it. However, there is no way to understand the stresses felt by living and growing bacteria (what stress they feel, how large it is, how important it is). It is necessary to compare standard stress levels to a low-stress state, but there was previously no method of creating a low-stress condition. This study developed a novel incubation device that produces very fine microbubbles and eliminates stress caused by bubble flow. Major stresses influential to bacterial growth and survival were revealed by using this device and gene expression analysis. Controlling the level of stress (stress management) on bacteria will be an invaluable ecological tool in the future; potential applications include better disinfectants and water purification.
