Abstrakt: Bacteria use a communication system, called quorum sensing (QS), to organize into communities and synchronize gene expression to promote virulence and secure survival. Here we report on a proof-of-principle for externally interfering with this bacterial communication system, using light. By employing photoswitchable small molecules, we were able to photocontrol the QS-related bioluminescence in an Escherichia coli reporter strain, and the expression of target QS genes and pyocyanin production in Pseudomonas aeruginosa .
