Figure 6From: Lactate production yield from engineered yeasts is dependent from the host background, the lactate dehydrogenase source and the lactate exportLactate production and yield obtained from recombinant GRF18U host cells. Different recombinant S. cerevisiae GRF18U cells were shake-flask grown in glucose 2% wv-1 minimal selective medium till stationary phase. Samples were collected at indicated times (h) for lactate (g l-1) and yield (gram of lactate produced per gram of glucose consumed; values are here below reported) determinations. () B. taurus LDH yield 4% ± 0.2% (☍) L. casei LDH yield 21% ± 0.4% (■) L. plantarum LDH yield 31% ± 0.5% (□) L. plantarum LDH + ScJEN 1 yield 39% ± 0.5% (●) Mutated L. plantarum LDH. yield 52% ± 0.7%Back to article page
