Fig. 3From: Electrode-assisted acetoin production in a metabolically engineered Escherichia coli strainGrowth analysis of the generated fermentation mutants. Genotypes: WT (DHαZ1), JG11 (Δfrd), JG369 (Δfrd ΔadhE), JG472 (Δfrd ΔadhE ΔldhA), and JG806 (Δfrd ΔadhE ΔldhA Δpta–ack). Growth rates and final values for the optical density are shown for the deletion mutants compared to the initial strainBack to article page
