Biologically catalyzed carbon dioxide mineralization using yeast-displayed enzymes and proteins
- Technology Benefits
- -Carbonate minerals are geologically stable and will not be released into the atmosphere-High storage capacity and long storage lifetime-Low materials cost-Can operate in near-standard conditions
- Technology Application
- Remove carbon dioxide from flue gas of power plants and convert it to carbonate minerals.
- Detailed Technology Description
- None
- *Abstract
-
Problem:Carbon dioxide in flue gas is a major cause of global warming, increasing atmospheric carbon dioxide levels.Technology:This invention describes a biologically catalyzed carbon dioxide mineralization process that uses yeast-displayed proteins and peptides. The yeast, Saccaramyces cerevisae, is used to manufacture and immobilize proteins and peptides. This can be used to enhance the mineralization rate of carbon dioxide and to control the crystal properties of the mineralized carbon dioxide. This also allows for easy recapture and re-use of the proteins and peptides.
