Carbonic Anhydrase: An Efficient Enzyme with Possible Global Implications

Figure 1

Schematic of the centralized role for CA in converting CO₂ into beneficial products. The catalytic conversion of CO₂ produced during the combustion of fossil fuels into bicarbonate (HCO₃⁻) via CA yields a valuable source of inorganic carbon for algal cultures grown in raceway ponds. The lipids and oils from the algae cultures are excellent sources for biofuels, whereas the “waste” product yields additional beneficial proteins, vitamins, minerals, and dietary supplements. The algal CA can also serve as a great source for calcite (CaCO₃) production, being critical in many construction, agricultural, and industrial materials.
