Syngas Fermentation for Bioethanol and Bioproducts

Abstract Production of biofuels and bioproducts from syngas or industrial waste gases, containing C1 compounds such as CO and CO 2 , is a promising alternative to the technologies used in conventional chemical industries and refineries. Various parameters and strategies that can improve the production process are addressed, focusing mainly on bioethanol. The advantages of fermentation over the thermochemical process using syngas as feedstock are discussed. Aspects of the Wood-Ljungdahl pathway and energy conservation mechanism in acetogens are included, and results from various batch assays and continuous studies performed in different bioreactor configurations to improve productivity are reviewed. Although interest in syngas fermentation has progressively increased in the recent years, research is needed to further optimize the process. Mass transfer of gas to liquid phase and the need to achieve higher biomass concentrations are still some main bottlenecks of the syngas fermentation process.
