Abstract:
Sulfurihydrogenibium  sp. carbonic anhydrase (SspCA) or mutants thereof catalyze a hydration reaction of CO 2  into bicarbonate and hydrogen ions or a desorption reaction to produce a CO 2  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 CO 2  from a CO 2 -containing gas.

Claim (Index 16):
