Carbonic anhydrase immobilized silk hydrogel and conversion or fixation of carbon dioxide using the same

摘要

The present invention relates to carbonic anhydrase-immobilized silk hydrogel and the conversion or the fixation of carbon dioxide using the same. According to the present invention, the carbonic anhydrase-immobilized silk hydrogel or a composition comprising the same is dual crosslinked by the photocrosslinking and alcohol treatment, thereby being eco-friendly and economic, having excellent thermal and storage stability, and being used in a repeated manner. The carbonic anhydrase-immobilized silk hydrogel or the composition comprising the same has significantly excellent effects of enzymatic activities, thereby removing, converting, or fixing carbon dioxide.
