“…Additionally, overexpression of CA and PCK in Corynebacterium acetoacidophilum ( ΔldhA ) increased SA production from 24.0 to 27.9 g/L and CFR from 0.299 to 0.347 g/L/h ( Qian and Zheng, 2023 ). Notably, the direct substrate of carboxylases is not CO 2 but HCO 3 − ( Craveiro et al, 2022 ; Zaidi et al, 2022 ) . CA could accelerate the conversion of CO 2 to bicarbonate, so its expression could increase the solubilization of CO 2 in intracellular fluids so that enzymes such as PEPC or PCK could make better use of HCO 3 − .…”

Succinic acid (SA), one of the 12 top platform chemicals produced from biomass, is a precursor of various high value-added derivatives. Specially, 1 mol CO2 is assimilated in 1 mol SA biosynthetic route under anaerobic conditions, which helps to achieve carbon reduction goals. In this review, methods for enhanced CO2 fixation in SA production and utilization of waste biomass for SA production are reviewed. Bioelectrochemical and bioreactor coupling systems constructed with off-gas reutilization to capture CO2 more efficiently were highlighted. In addition, the techno-economic analysis and carbon sequestration benefits for the synthesis of bio-based SA from CO2 and waste biomass are analyzed. Finally, a droplet microfluidics-based high-throughput screening technique applied to the future bioproduction of SA is proposed as a promising approach.
