Fluorescence intensity of colonies harbouring pGESS or pHCEIIB-egfp on LB and M9 4 g/L glucose agar plates. (a) Microscopic image of single colonies harbouring the pHCEIIB-EGFP on LB and M9 agar plates. Image processing and analysis were performed using Nikon’s NIS-Elements AR 4.2 software. (b) Fluorescence intensity and colony density profile. (c) Microscopic image of single colonies harbouring pGESS on LB and M9 agar plates containing 100 μM phenol. (d) Fluorescence intensity and colony density profile.
