Growth, respiration, and 13C-labeling of strains P. putida NCIB 8616-4 and P. putida NCIB 8616-4 C on a mixture of 13C-glucose and unlabeled naphthalene. (A) Growth in MSB amended with unlabeled naphthalene crystals and 0.1% 13C-glucose. (B) Production of labeled and unlabeled CO2 respired during growth on the substrates shown in (A). (C) Mass 27 and 26 signal intensities for individual wild-type (wt) or cured P. putida NCIB 9816-4 cells after growth on the media in (A). Signal intensities were measured with Metamorph® software.
