Fig. 2From: Metabolic engineering design to enhance (R,R)-2,3-butanediol production from glycerol in Bacillus subtilis based on flux balance analysisTime courses of growth, glycerol utilization, and VFAs production for B. subtilis strains as follows W168 (A), W168∆2 (B), W168∆3 (C), and W168∆4 (D). The data are presented as the mean ± standard deviation of three independent experiments (n = 3)Back to article page
