Physiological characterization of the strain OG2 in bioreactor. a Growth-curve (optical density at 600 nm) profile and butanol concentration; b glucose and end-products concentrations during the fermentation and c specific growth rate (µ), duplication time (td) and butanol, ethanol, succinate, acetate and lactate yields (Y) on glucose. Cells were cultivated aerobically in HDM medium and induced with 0.5 mM of IPTG at 0.4–0.5 OD600. At this moment, anaerobic conditions were created by turning off the air flow and waiting for the leftover oxygen to be consumed. Data are shown as mean ± SD of three independent experiments. ButOH butanol, EtOH ethanol, Succ succinate, Acet acetate, Lact lactate
