Effect of Sorghum vulgare phosphoenolpyruvate carboxylase and Lactococcus lactis pyruvate carboxylase coexpression on succinate production in mutant strains of Escherichia coli.

Abstract excerpt

Sorghum vulgare phosphoenolpyruvate carboxylase (PEPC) and Lactococcus lactis pyruvate carboxylase (PYC) were overexpressed in Escherichia coli concurrently to improve the production of succinate, a valuable industrial specialty chemical. This coexpression system was also applied to E. coli mutant strains strategically designed by inactivating the competing pathways of succinate formation. The highest level of...
