Abstract: The present description relates to recombinant or engineered carbonic anhydrase polypeptides, variants, and functional derivatives thereof, having improved properties that make them advantageous for use in CO2 capture operations (e.g., CO2 capture solvents, alkaline pH, and/or elevated temperatures), as well as polynucleotides and vectors encoding same. The present description also relates to methods, processes and systems for CO2 capture which make use of the recombinant or engineered carbonic anhydrase polypeptides, variants, and functional derivatives thereof.

Abstract: Sulfurihydrogenibium sp. carbonic anhydrase (SspCA) or mutants thereof catalyze a hydration reaction of CO2 into bicarbonate and hydrogen ions or a desorption reaction to produce a CO2 gas. Sulfurihydrogenibium sp. carbonic anhydrase (SspCA) having improved thermostability in the presence of carbonate ions as compared to in the absence of carbonate ions are useful in the capture of CO2 from a CO2-containing gas.
