摘要
Methods and systems for producing short carbon chain weak organic acids (e.g., acetic acid) from a gas stream rich in carbon dioxide. The systems include a liquid-gas contact unit a flue gas desulfurization unit), and a bacterial strain disposed in the liquid-gas contact unit. The bacterial strain reduces a concentration of carbon dioxide in the gas stream, and produces one or more organic acids (e.g., acetic acid, butyric acid, propionic acid, lactic acid, or combinations thereof). Related methods include providing a gas stream rich in carbon dioxide, introducing the gas stream into a liquid-gas contact unit, preparing an inoculum comprising a bacterial strain adapted to produce organic acid(s) from the carbon in the gas stream, and inoculating the liquid-gas contact unit with first amount of the inoculum such that the bacteria therein consume carbon dioxide from the gas stream, producing the organic acid(s).
