Composition for CO2 capture comprising marine bacterium-derived recombinant biocatalyst Method for preparing the same and Method of CO2 capture using the same

摘要

The present invention relates to a method for producing a microorganism capable of promoting the hydration reaction of carbon dioxide, which is derived from marine bacteria, specifically, Hydrogenovibrio marinus a transformant obtained by expressing a marine- derived carbonic anhydrase, a cell lysate of the transformed cell or a fraction thereof, or a carbonic anhydrase isolated from the transformed cell, and having excellent stability against temperature and pH A composition for capturing carbon dioxide as a biocatalyst, a method for producing the same, and a method for collecting carbon dioxide using the same. The carbonic anhydrase derived from marine bacteria of the present invention can maintain excellent activity even at various pH ranges and at high temperatures and thus can be very usefully applied to an actual carbon dioxide capture process. In addition, since it can be mass-produced by using the E. coli system, it has an advantage in terms of economy.
