Concerns about global warming have dramatically increased interest in the development of a strategy for the sustainable and economical fixation of carbon dioxide (CO2). Biofixation of CO2 is believed to be both economically and environmentally advantageous, moreover, achieving treatment of high-concentration CO2 is a significant goal for efficient fixation. In this study, a deep-sea sulfur-oxidizing bacterium was used for the biofixation of CO2 in the range of CO2 pressure from 0.3 atm to 2 atm at 29°C. The optimal culture condition is determined through the various pH ranges. It exhibited fast specific fixation rate of approximately 0.42 g CO2 g cell-1 hr-1. Moreover, the metabolites were identified as the dominant species through metabolomics analysis. |
