Korean researchers use acetogen to ferment syngas and ethanol

In South Korea, researchers from the Gwangju Institute of Science and Technology and from Korea University have developed technology to produce commercially-viable syngas and C1 gas from biomass, waste or byproduct gas by using acetogen to absorb CO2 and produce metabolite acetic acid. Syngas fermentation can then be used to produce ethanol, butyric acid, and butanol. Using this concept, the team then produced ethanol via ethanologenesis, similar to acetogenesis, which allowed the researchers to overcome the limitation of mixed production generation.
