glucose is fermented to form the intermediate
sodium succinate. The salt is converted to succinic
acid and base by water-splitting electrodialysis, fol-
lowed by recycling of the base to the fermentation
step. Concentrations of succinic acid as high as

Production of BDO based on bioderived succinic

recently, an approach based on the use of an engi-
neered
E. coli
bacterium has been shown to be effec-
tive on a commercial scale (Scheme 14.22) [131].
The process is being commercialized currently by
Applied CarboChemicals, Inc. In this new process,
