Fig. 2From: Investigation of two metabolic engineering approaches for (R,R)-2,3-butanediol production from glycerol in Bacillus subtilisFermentation profiles, including growth, glycerol utilization, and VFA production of B. subtilis strains. Data for the following strains are shown: W168 (A), LM01 (B), and MZ02 (C). The data are presented as the mean ± standard deviation of three independent experiments (n = 3)Back to article page
