Abstract excerpt
The evolved mutant Escherichia coli E2 previously developed for succinate production from glycerol was engineered in this study for fumaric acid production under aerobic conditions. Through deletion of three fumarases, 3.65g/L fumaric acid was produced with the yield of 0.25mol/mol glycerol and a large amount of acetate was accumulated as the main byproduct. In order to reduce acetate production several...
