Mondem S. Reddy, Sumit Joshi, in Carbon Dioxide Sequestration in Cementitious Construction Materials, 201810.4.2 Enzyme involved in CO2 sequestrationCarbonic anhydrase (CA) is the first-discovered zinc-containing metalloenzyme that is widespread in animals, plants, and microorganisms that catalyses the conversion of CO2 and water into bicarbonate (Smith and Ferry, 1999). The CA is widespread in metabolically diverse species of bacteria indicating that this enzyme plays a significant role in concentrating CO2 (Dhami et al., 2014). In natural process of photosynthetic assimilation of CO2, CA enzyme acts as biocatalyst (Jansson and Northen, 2010). Potential role of CA enzyme in addressing environmental issues such as reducing carbon emissions through CO2 sequestration has gained considerable attention. CA enzyme is reported to be a potential tool to sequester CO2 from emission sources (Bose and Satyanarayana, 2017). It was reported that partially purified CA from B. pumilus immobilized on chitosan beads has improved calcium carbonate precipitation than free CA enzyme in carbonation reaction (Wanjari et al., 2011). Immobilization of CA enzyme into alginate beads showed better operational stability by retaining nearly 67% of its initial activity and entrapped CA hydrates CO2 to bicarbonate and/or carbonate, which on reaction with Ca2+ ions, transform into calcite (Yadav et al., 2012). It was reported as a commercialized development for the onsite scrubber for CO2 sequestration. Zhang et al. (2011) reported the effective absorption of CO2 into the potassium carbonate solution with biocatalyst CA immobilized into controlled pore glass material. The immobilized enzyme retained at least 60% of their initial activities and significantly improved resistance to concentrations of sulfate (0.4 M), nitrate (0.05 M), and chloride (0.3 M) conditions in flue gas expected in the Integrated Vacuum Carbonate Absorption Process.
