Quorum sensing (QS) is the bacterial cell‐to‐cell communication system regulated by the concentration of n‐acylhomoserine lactone (AHL) as the main signaling molecule in gram‐negative bacteria. QS is inhibited by β–cyclodextrin (β–CD)‐modified core‐shell microspheres. On page 43198 (1 of 7), Chigusa Okano, Eri Nasuno, Ken‐ichi Iimura and Norihiro Kato confirm the effective trapping of the AHL on CDs using a bioassay with the AHL‐negative mutant Chromobacterium violaceum CV026. The impact of the quenching effect is successfully demonstrated by a change in color tone of the Serratia marcescens AS‐1 culture, because the production of the red pigment prodigiosin is enabled to reduce by inhibitory expression of a QS‐dependent gene, pig cluster , in the AS‐1 strain.
