Schematical overview of the vectors used in this study. A physical map for relevant restriction endonucleases is given for the plasmid pJOE4056.1 and the location and orientation of the rhaP_BAD promotor, the genes encoding eGFP, ampicillin resistance (bla), rop and addiction modules ccdA and ccdB are indicated by triangle and arrows. The transcription terminator sequence (ter) is derived from the E. coli rrnB operon.
