Metabolic engineering of S. elongatus to produce isobutanol. A Enzymes that catalyze the metabolic pathway from pyruvate to isobutanol. B Schematic representation of recombination to integrate kivd, adhA, alsS, ilvC and ilvD into the S. elongatus genome. C, D Growth curves (C) and isobutanol production titers (D) of engineered S. elongatus. Black diamond: cultivation of JW10 (plasmid pAM2991 integrated in S. elongatus) in BG11. White diamond: cultivation of JW11 (plasmid pJW12 integrated in S. elongatus) in BG11. Circle: cultivation of JW11 in BG11 with 1.47% NaCl. Up-pointing triangle: cultivation of JW11 in BG11 with 2% sea salt
