Physiological characteristics assessment of the GIs-deleted mutants of P. putida KT2440. a Growth curves of the P. putida mutants in M9 minimal medium. b Growth curves of the P. putida mutants in LB medium. c The efficiency for transformation of the plasmid pBBR1MCS-2 into the P. putida mutants. d The relative fluorescence intensities of the P. putida mutants grown in M9 minimal medium. e The relative fluorescence intensities of the P. putida mutants grown in LB medium. P. putida KTU was used as a control in all measurements. The data are mean values ± standard deviations from three replicates
