Lactate 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%
