Product yield on glucose on selected products after 72 h of anaerobic fermentation for strains based on ΔldhA ΔackA (ΔΔ) with further modifications for improved hydrogen production, from left to right: inactivation of hycA, hyaAB and hybBC (ΔΔΔΔΔ), overexpression of fhlA (ΔΔ p3-fhlA) and a combination of knockouts and overexpression (ΔΔΔΔΔ p3-fhlA). Values are averages of two biological replicates and error bars represent standard deviations
