英文摘要: The utilization of the juice from the cheapest carbon source oil palm frond (22 $/ton) in a 3.5 L bioreactor was proven to be competent in replacing pure sugar in succinic acid production. The current study provides an in-depth discussion on the utilization of CO2 in the production of succinic acid. In the serum-bottle fermentation, the yield of succinic acid increased by 51% from 0.47 to 0.71 g/g while the final titer of succinic acid enhanced by 4 fold were attributed to the anaplerotic reaction of Actinobacillus succinogenes and the alkalinity effect of the dissolved CO2. In the bioreactor, the highest mass transfer in the fermentation medium was achieved at 0.5 vvm CO2 at which 3 M KOH was pumped in at a rate of 2.0 mL/min to neutralize the carbonic acid formation, which afforded the highest succinic acid concentration of 30.7 g/L. A first report on actual stoichiometry equation relating substrate, CO2 consumption and all products formation was derived from the results of bioreactor fermentation to lay as a guideline for future reference of actual succinic acid production reaction. C6H12O6 + 0.145 NH3 + 0.642 CO2 → 1.083 C4H6O4 + 0.509 CH2O2 + 0.420 C2H4O2 + 0.117 C2H5OH + 0.726 CH1.8N0.2O0.5 + 0.614 H2O. Actual stoichiometry equation revealed that for every kg of succinic acid produced, 0.22 kg of CO2 will be absorbed. The desirable effect of CO2 on the production of succinic acid may translate into a mutually-beneficial relationship between the succinic acid and the CO2-generating biofuel industries. © 2018 Elsevier Ltd.
