Abstract: Pseudomonas putida F1 can metabolize toluene, ethylbenzene, and benzene for growth. Previously, we identified proteins involved in the utilization of these compounds by P. putida F1 through culture in liquid media. However, it was unclear whether laboratory analysis of bacterial activity and catabolism accurately reflected the soil environment. We identified proteins involved in the degradation of toluene, ethylbenzene, and benzene growth in soil using two-dimensional gel electrophoresis (2-DE) or standard SDS-PAGE combined with liquid chromatography–tandem mass spectrometry (LC–MS/MS). According to 2-DE/LC–MS/MS analysis, 12 of 22 key enzymes involved in the degradation of toluene, ethylbenzene, and benzene were detected. In standard SDS-PAGE/LC–MS/MS analysis of soil with ethylbenzene, approximately 1,260 cellular proteins were identified in P. putida F1. All key enzymes and transporter and sensor proteins involved in ethylbenzene degradation were up-regulated similar to that noted in liquid cultures. In P. putida F1, aromatic hydrocarbon response in soil is the same as that observed in liquid media.
