METHOD FOR THE FIXATION OR CONVERSION OF HIGH-PRESSURE CARBON DIOXIDE USING BAROPHILIC SULFUR-OXIDIZING CHEMOLITHOAUTOTROPHS

摘要

The present invention relates to a method for biologically treating carbon dioxide using the sulfur-oxidizing chemolithoautotroph Sulfurovum lithotrophicum 42BKT. The method for the fixation or conversion of carbon dioxide using Sulfurovum lithotrophicum 42BKT according to the present invention may enable carbon dioxide to be fixed or converted in high-concentration and high-pressure conditions which do not allow the biological photosynthetic conversion of microalgae or the like, and may exhibit high efficiency in the fixation of carbon dioxide as compared to existing methods for biologically treating carbon dioxide using microalgae. Further, the method of the present invention may use a mixture gas without a process of separating nitrogen and other gases, which might be required in a biological treatment of carbon dioxide, thus simplifying the process of the fixation or conversion of carbon diode. Thus, according to the present invention, high-pressure carbon dioxide can be treated in an efficient and safe manner by means of the biological conversion of the high-pressure carbon dioxide, and biomass having a high added value can be obtained.
