Outline of Final Research Achievements |
Inhibition of quorum sensing is a promising approach as a next-generation infection treatment unlike antibiotics which kill bacteria. In this study, it was investigated if bacteria can have a certain ability to alleviate or avoid repression effect by quorum sensing inhibition. Therefore, a resistant strain to quorum sensing inhibition was screened under the condition in the presence of adenosine as a sole carbon source as utilization of adenosine is required by the function of quorum sensing. As a result, mexR and nalC genes in Pseudomonas aeruginosa were related to the resistance to quorum sensing inhibition and also Pseudomonas aeruginosa was able to biotransform a quorum sensing inhibitor.
