From: Co-production of hydrogen and ethyl acetate in Escherichia coli
Concentrations of glucose and products after 72 h of anaerobic cultivation for strains with a ΔldhA ΔackA (ΔΔ) background and further modifications for improved hydrogen production, from left to right: inactivation of hycA, hyaAB and hybBC (ΔΔΔΔ), overexpression of fhlA (ΔΔ p3-fhlA) and a combination of knockouts and overexpression (ΔΔΔΔ p3-fhlA). For CO2 and H2, data represent calculated concentrations. Data show average values and standard deviations from biological duplicates
