20130206685 | METHOD FOR FIXING CARBON DIOXIDE AND COMPOSITION THEREFOR - Provided is a method for biologically fixing carbon dioxide dissolved in contaminated water using a microorganism derived from rhodolith. The method includes enrichment-incubating a microorganism derived from rhodolith, and treating and reacting the enrichment-incubated microorganism in contaminated water to fix carbon dioxide dissolved in contaminated water as a carbonate mineral. The method for biologically fixing carbon dioxide has a simple fixing process and is environmentally friendly, compared with chemical carbon dioxide fixing technology. In addition, this method enables fast fixation of carbon dioxide even at room temperature, and thus can be easily applied in the industrial field, and is also useful in an aspect of resource recycling since the carbon dioxide is eventually fixed in the form of calcium carbonate. | 08-15-2013 |
