Expression of biosensor PcdrA-gfp (a) and Ppel-lacZ (b) by P. aeruginosa strains in ABTGC medium with and without the presence of 10 μg/ml TeO32−. The PcdrA-gfp expression was shown as relative fluorescence units (RFU) per OD600. The Ppel-lacZ expression was shown as Miller Unit. Means and standard deviations of three replicates are shown. Student’s t-test was performed for testing differences between groups. * P < 0.05.
