“…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.

“…Covalent binding implies the formation of bonds between the groups of adequately functionalized supports and an enzyme. This is, by far, the most extended approach for immobilizing enzymes, particularly for CA [ 152 , 155 , 178 , 179 ]. Several protein functional groups can be used for this purpose.…”

Direct Biocatalytic Processes for CO2 Capture as a Green Tool to Produce Value-Added Chemicals

et al. 2023

Direct biocatalytic processes for CO2 capture and transformation in value-added chemicals may be considered a useful tool for reducing the concentration of this greenhouse gas in the atmosphere. Among the other enzymes, carbonic anhydrase (CA) and formate dehydrogenase (FDH) are two key biocatalysts suitable for this challenge, facilitating the uptake of carbon dioxide from the atmosphere in complementary ways. Carbonic anhydrases accelerate CO2 uptake by promoting its solubility in water in the form of hydrogen carbonate as the first step in converting the gas into a species widely used in carbon capture storage and its utilization processes (CCSU), particularly in carbonation and mineralization methods. On the other hand, formate dehydrogenases represent the biocatalytic machinery evolved by certain organisms to convert CO2 into enriched, reduced, and easily transportable hydrogen species, such as formic acid, via enzymatic cascade systems that obtain energy from chemical species, electrochemical sources, or light. Formic acid is the basis for fixing C1-carbon species to other, more reduced molecules. In this review, the state-of-the-art of both methods of CO2 uptake is assessed, highlighting the biotechnological approaches that have been developed using both enzymes.

“…15 Carbonic anhydrase (CA), a zinccontaining metalloenzyme, plays a vital role in photosynthetic carbon capture by efficiently catalyzing the hydration of CO 2 . 16,17 Free CA exhibits high catalytic efficiency in a liquidphase environment, facilitating extensive contact with CO 2 during catalytic reactions. However, the structural instability of CA makes it susceptible to deformation, resulting in a loss of catalytic activity in complex industrial environments.…”

“…By immobilizing CA onto various materials, the stability of the enzyme's protein structure can be preserved, reducing its susceptibility to deactivation caused by environmental factors. 17,20,21 Additionally, reusing substrates can realize the recycling of CA, which lowers industrial costs.…”
