Confirmation of AHL-degradation activity. (a) TLC analysis using the biosensor Agrobacterium tumefaciens NTL4 (pZLR4). (b) HPLC/MS measurements of remaining C6-HSL and C12-HSL after 24 h incubation with E. coli S17 λ pir and E. coli S17 λ pir::f10/17.1H. LB medium was used as control. Initial AHL concentration was 25 µM. Error bars represent standard deviations. Different letters above the bars indicate that the values are significantly different according to a one-factor (treatment) ANOVA (P < 0.05) and the Tukey test.
