Comparison of metabolites production, cell growth, and glucose consumption profile by wild-type (WX-02) and bud C knock-out (WX-02 Δ bud C) B. licheniformis strains. (A) D- and meso-2,3-butanediol production. (B) Total 2,3-butanediol and acetoin production. (C) Cell density, medium pH, and residual glucose concentration. Data are expressed as mean ± standard errors of three replicates. BDL, butanediol.
