Pseudomonas putida strains are prevalent in a variety of pristine and polluted environments. The genome of the solvent-tolerant P. putida strain DOT-T1E which thrives in the presence of high concentrations of monoaromatic hydrocarbons, contains a circular 6.3 Mbp chromosome and a 133 kbp plasmid. Omics information has been used to identify the genes and proteins involved in solvent tolerance in this bacterium. This strain uses a multifactorial response that involves fine-tuning of lipid fluidity, activation of a general stress-response system, enhanced energy generation, and induction of specific efflux pumps that extrude solvents to the medium. Local and global transcriptional regulators participate in a complex network of metabolic functions, acting as the decision makers in the response to solvents. © 2012 Federation of European Biochemical Societies.
