| 520 | 3 | |a We previously reported on the impacts of the overexpression of individual genes of the glycolytic pathway encoding glucokinase (GLK), glyceraldehyde phosphate dehydrogenase (GAPDH), phosphofructokinase (PFK), triosephosphate isomerase (TPI), and bisphosphate aldolase (FBA) on D-lactate productivity in Corynebacterium glutamicum under oxygen-deprived conditions. Searching for synergies, in the current study, we simultaneously overexpressed the five glycolytic genes in a stepwise fashion to evaluate the effect of the cumulative overexpression of glycolytic genes on D-lactate production. Interestingly, the final D-lactate concentration markedly differed depending on whether or not the PFK encoding gene was overexpressed when combined with overexpressing other glycolytic genes. The simultaneous overexpression of the GLK, GAPDH, TPI, and FBA encoding genes led to the highest initial D-lactate concentration at 10h. However, this particular recombinant strain dramatically slowed producing D-lactate when a concentration of 1300mM was reached, typically after 32h. In contrast, the strain overexpressing the PFK encoding gene together with the GLK, GAPDH, TPI, and FBA encoding genes showed 12.7% lower initial D-lactate concentration at 10h than that observed with the strain overexpressing the genes coding for GLK, GAPDH, TPI, and FBA. However, this recombinant strain continued to produce D-lactate after 32h, reaching 2169mM after a mineral salts medium bioprocess incubation period of 80h. These results suggest that overexpression of the PFK encoding gene is essential for achieving high production of D-lactate. Our findings provide interesting options to explore for using C. glutamicum for cost-efficient production of D-lactate at the industrial scale. | |
