Detection of Quorum Sensing N-acylhomoserine lactones Signal Molecules

Abstract: Many Gram-negative bacteria use N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signal molecules to communicate with each other， synchronize related gene expression and response collectively to a changing environment. Bacterial quorum sensing plays essential roles in controlling and coordinating a variety of bacterial behavior. Simple and effective protocols for detecting and analyzing various signal molecules are of importance for identifying and understanding bacterial quorum sensing. The present article introduces and discusses the currently available microbial sensor strains used in detecting different kinds of AHLs.
