| Escherichia coli KO11 and Klebsiella oxytoca P2 recombinants fermented sucrose to ethanol. In minimal medium with 2% or 12% added sucrose KO11 produced 75% and 41%, respectively, of the maximum theoretical yield (0.54g ethanol/g sucrose). In Luria-Bertani (LB) broth with up to 8% sucrose, KO11 presented a 94-96% yield and with 12% sucrose, KO11 presented about 69% yield (44.5g ethanol/L). P2 presented 55% of the theoretical maximum yield in minimal medium supplemented with 2% sucrose and 47% of the maximum in 12% sucrose. In LB broth with 2 or 4% sucrose, P2 presented 94-95% of the theoretical maximum yield, which fell to 73% with 8% added sucrose (31.4g ethanol/L) and 58% with 12% sucrose (37.5 g/L). Volumetric productivity in LB broth containing 2%... |
