The TOL plasmid, pWWO, conjugally transferred from Pseudomonas putida mt-2 was dissociated into TOL* and TOL $\Delta$A in P. putidu PpGl carrying CAM plasmid. The TOL* was integrated into the CAM plasmid, and the resulting plasmid was designated as CAM::TOL*. The introduction of NAH plasmid, belonging to Inc P9 incompatibility group, into P. putida CSTBA carrying CAM::TOLt plasmid and TOL A plasmid did not affect m-toluate catabolism, but resulted in expelling the TOL $\Delta$ plasmid.
