p.7 left column top paragraph:"Importantly, the dilution rate effectively modifies the degradation rate of the signaling molecule. In this regard, while some bacteria species have hydrolytic enzymes that degrade AHLs, generally speaking, bacteria that synthetize AHLs do not degrade them enzymatically. In fact, AHLs are chemically stable species in aqueous solutions [primary source]. The degradation rate of the homoserine lactone 3-Oxo-C6-AHL has been measured in vitro revealing that this autoinducer is rather stable: ~ 3·10^−4 min^−1 [primary source]. Measurements of the degradation rate of other AHL autoinducers show similar results." AHL=acyl homo-
