The effects of CO₂ and H₂ on CO metabolism by pure and mixed microbial cultures.

ABSTRACT:

Background

Syngas fermentation, the bioconversion of CO, CO₂, and H₂ to biofuels and chemicals, has undergone considerable optimization for industrial applications. Even more, full-scale plants for ethanol production from syngas fermentation by pure cultures are being built worldwide. The composition of syngas depends on the feedstock gasified and the gasification conditions. However, it remains unclear how different syngas mixtures affect the metabolism of carboxidotrophs, including the ethanol/acetate ratios. In addition, the potential application of mixed cultures in syngas fermentation and their advantages over pure cultures have not been deeply explored. In this work, the effects of CO₂ and H₂ on the CO metabolism by pure and mixed c
