Degradation of AHLs by GG2 and Se14. Degradation of AHL: + : weak; ++ : moderate; + + + : significant. Insets denote the digital image of AHLs detected using the biosensors E. coli [pSB401] and/or E. coli [pSB1075]; evaluated according to the reduction in bioluminescence. All experiments took into account the detection limit of the biosensors used for each AHL-degradation assay.
