TtgABC expression increases survival of Pseudomonas putida DOT-T1E in biofuels. Fraction of P. putida DOT-T1E cells surviving 2 h of incubation with a 1.9% n-butanol b 2.2% isobutanol, c 1.5% isoprenol, and d 0.7% isopentanol. Cells carrying TtgABC on a plasmid with l-arabinose inducible promoter were grown with (ttgABC+) or without (ttgABC) inducer. Plasmid-free wild-type cells (WT) were grown with l-arabinose as control. Ratios were obtained by sampling viable cell numbers before and after incubation. The error bars indicate minimum and maximum of 3–6 biological replicates
