Abstract
The present invention generally relates to improvements in enzyme immobilization, particularly for use in the field of carbon dioxide capture and sequestering. It has been discovered that the utilization of sol-gel processes to immobilize enzymes in polysilicate-polysilicone copolymer coatings and particles, and the deposition of these coatings on solid state supports or use of suspensions of these particles, provides significant benefits for use in industrial applications involving enzymatic catalysts.
Claims25
A coated support comprising a polysilicate-polysilicone copolymer immobilizing a biocatalyst;
- the polysilicate-polysilicone copolymer adhered to a solid support by an adhesive coating and wherein the biocatalyst comprises a carbonic anhydrase.
A coated support comprising
- a solid support;
- a coating composition forming a layer on the surface of the solid support, the coating composition comprising a polysilicate-polysilicone copolymer and a hydrophilic additive;
- and
- a biocatalyst that catalyzes hydration of carbon dioxide being entrapped in the coating composition;
- wherein the biocatalyst comprises a carbonic anhydrase.
