Figure 4From: Production of l-lactic acid by the yeast Candida sonorensis expressing heterologous bacterial and fungal lactate dehydrogenasesComparison between pdc1Δ::LhLDH pdc2Δ , pdc1Δ::BmLDH pdc2Δ , and pdc1Δ::RoLDH pdc2Δ strains. Lactate (A), pyruvate (B) and glucose (C) concentrations in YP+ 5% glucose medium by the pdc1Δ ::LhLDH pdc2Δ (⋄), pdc1Δ ::BmLDH pdc2Δ (□), pdc1Δ ::RoLDH pdc2Δ (∆) or pdc1Δ pdc2Δ (○, no LDH) strains. (D). The final yields of lactate (black), pyruvate (descending diagonal) and biomass (grey) on glucose, determined at 120 h. (E). LDH enzyme activities determined at 20 h (1) and 40 h (2). FBP, 5 mM fructose-1, 6-diphosphate. Data are means ± SEM.Back to article page
