| 초록 | Nowadays more concerns are increasing on the discharge of CO2 to atmosphere due to global warming problems. CCS (carbon capture and sequestration) has been actively pursued to address CO2 accumulation problem in atmosphere, however there are desperate demand for technology to convert CO2 to value added chemicals. Even though formate dehydrogenase was reported to reduce CO2 to formate, most formate dehydrogenase showed much higher oxidation activity of formate rather than reduction activity of CO2. In this presentation we searched and expressed several formate dehydrogenases as recombinant protein to find formate dehydrogenase showing higher reduction activity for CO2. In addition, since reduction reaction of CO2 to formate can be favored at low pH, acid tolerant formate dehydrogenase will be more promising. Formate dehydrogenases from genome of acid tolerant microbial such as Thiobacillus showed higher activity to synthesize formate from CO2 at acidic pH condition. |
