Exploring environmentally friendly ways of converting biodegradable organic materials such as biomass and activated sludge to biofuels and chemicals have drawn worldwide interest. Syngas fermentation provides a new platform for organic waste utilization. In this study, basic metabolic pathways—the Wood–Ljungdahl pathway and reverse β-oxidation reaction and thermodynamics—are summarized in Sect. 2. The operating conditions—pH, temperature, CO and H2 partial pressure, syngas impurities, and reactor configuration that could change the microbial community or the metabolic pathway—are discussed in Sect. 3. Lastly, coupling syngas fermentation with other technologies, such as syngas pretreatment and membrane technology, was necessary for its application. Such application is summarized in the last section. Other promising technologies, such as polyhydroxyalkanoate production and microbial fuel cells, are also reviewed. This chapter reviews recent advances in syngas fermentation to promote the development and application of syngas fermentation worldwide.
