“…Thus, carbon mineralization, where CO2 is reacted with metal cations such as calcium to form calcium carbonate (CaCO3), is considered an effective alternative to conventional geologic sequestration [61]. Note that bivalve shell composed of CaCO3 is abundant and stable biomaterials in ocean [62]. This process can be seen in Equations (2)-(6) below:…”

“…However, in the whole process, H2CO3 formation is the rate-limiting step [63]. Thus, CA has recently been utilized to enhance CO2 sequestration through the conversion and mineralization of CO2 into CaCO3 [62]. The converting CO2 into carbonate compounds by using CA as a catalyst in a biomimetic approach is thermodynamically advantageous compared to other CO2 storage methods and technologies.…”

Turning carbon dioxide (CO 2 ) into fuels and chemicals using chemical, photochemical, electrochemical, and enzymatic methods could be used to recycle large quantities of carbon. The enzymatic method, which is inspired by cellular CO 2 metabolism, has attracted considerable attention for efficient CO 2 conversion due to improved selectivity and yields under mild reaction conditions. In this review, the research progress of green and potent enzymatic conversion of CO 2 into useful fuels and chemicals was discussed. Furthermore, applications of the enzymatic conversion of CO 2 to assist in CO 2 capture and sequestration were highlighted. A summary including the industrial applications, barriers, and some perspectives on the research and development of the enzymatic approach to convert CO 2 were introduced.

“…CA is one of the fastest known enzymes, with a k cat value of up to ϳ10 6 , almost 10 million times faster than the noncatalyzed natural reaction. This enzyme has been found in various organisms and is ubiquitous throughout the three domains of life, participating in distinct physiological functions, such as pH modulation, carbon concentration, and biomineralization (7).…”

Carbonic anhydrase is an enzyme that reversibly catalyzes the hydration of carbon dioxide (CO 2 ). It has been suggested recently that this remarkably fast enzyme can be used for sequestration of CO 2 , a major greenhouse gas, making this a promising alternative for chemical CO 2 mitigation. To promote the economical use of enzymes, we engineered the carbonic anhydrase from Neisseria gonorrhoeae (ngCA) in the periplasm of Escherichia coli, thereby creating a bacterial whole-cell catalyst. We then investigated the application of this system to CO 2 sequestration by mineral carbonation, a process with the potential to store large quantities of CO 2 . ngCA was highly expressed in the periplasm of E. coli in a soluble form, and the recombinant bacterial cell displayed the distinct ability to hydrate CO 2 compared with its cytoplasmic ngCA counterpart and previously reported wholecell CA systems. The expression of ngCA in the periplasm of E. coli greatly accelerated the rate of calcium carbonate (CaCO 3 ) formation and exerted a striking impact on the maximal amount of CaCO 3 produced under conditions of relatively low pH. It was also shown that the thermal stability of the periplasmic enzyme was significantly improved. These results demonstrate that the engineered bacterial cell with periplasmic ngCA can successfully serve as an efficient biocatalyst for CO 2 sequestration.

Mineralization has emerged as a promising strategy for long-term carbon sequestration. These processes involve carbon dioxide hydration followed by mineral precipitation. We have explored the production of whole-cell biocatalysts engineered with carbonic anhydrase (CA) activity to accelerate the CO₂ hydration reaction. In this study, short polypeptides were displayed on the surface of E. coli cells and whole-cell biocatalysts containing periplasmically expressed CAs in an attempt to enhance calcite mineral formation. It was found that cells coexpressing recombinant periplasmic CA and surface-displayed GPA peptide (PEVPEGAFDTAI) outperformed other peptide-expressing biocatalysts evaluated in terms of the amount of precipitate formed, as well as the overall formation rate of solids. Cells expressing the Cab CA isoform (BLR-pCab) and Cam isoform (BLR-pCam) with the surface-displayed GPA peptide exhibited 36 and 59% improvements in precipitation amounts, as well as 18 and 60% improvements in overall formation rates, respectively, over similar biocatalysts without GPA expression. The biocatalyst with the best performance was BLR-pCam/GPA, which generated 0.15 g of CaCO₃, while BLR cells generated only 0.08 g of CaCO₃ under the same small batch reaction conditions. The BLR-pCam/GPA cells also exhibited the fastest formation rates, achieving the maximum change in solution turbidity after only 2.2 min, as opposed to 6.3 min for BLR cells. These results demonstrate that synthetic biology approaches can be used to create novel biocatalysts with the ability to enhance both catalysis and precipitation activities.
