From: Metabolic engineering of Zymomonas mobilis for anaerobic isobutanol production
Isobutanol production of Z. mobilis recombinant strain ZMQ3-A4 in flask with different medium volumes of RMG5 medium (20, 50, or 80% flask volume) under the induction of different tetracycline concentrations of 0.2, 0.5 and 1.0 μg/mL, respectively. Tc 0, Tc 0.2, and Tc 1 represented the tetracycline concentrations of 0, 0.2, and 1.0 μg/mL that was added into the medium one time at the beginning of the experiment, respectively. The results shown are the mean of two technical replicates and the error bars represent standard deviations
