Fig. 4

Test-tube scale culture of SCM043 (wild-type), SCM051 (mpc1Δ), SCM042 (atg32Δ) strains for 2,3-butanediol fermentation. The black and gray bars represent ethanol and 2,3-butanediol titers, respectively. +23BD denotes the strains harboring the plasmid pATP426-als^Lp_Op-aldc^Ll_Op-BDH1 for 23BD production. Open diamonds represent the OD₆₀₀ of strains. Each value represents the standard deviation of three replicate fermentations
