Abstract The conversion of carbon dioxide to medium-chain fatty acids (CO 2 -to-MCFAs) through microbial processes represents a valuable technology for sequestering and exploiting CO , generating superior bio-chemicals from the primary contributor greenhouse effect. However, comprehensive overview generalization -to-MCFAs are presently deficient. Based on this, present review systematically summarizes research progress, explicates process mechanisms, analyses key challenges possible solutions, anticipates forthcoming perspectives priorities first time. We proposed two original strategies, namely synchronous strategy integrated strategy, current into -to-MCFAs. concurrently achieves hydrogen (H ) assimilation, as well MCFAs production, by employing reactor that co-cultivates predominant H /CO -utilizing microorganisms chain elongation microorganisms. approaches involve -to-precursors (i.e., acetate ethanol) subsequent precursors-to-MCFAs, achieved use bioreactors separately cultivating Mechanistic insights reveal predominantly encompasses processes: assimilation precursor precursors MCFAs, Wood-Ljungdahl pathway two-round elongation, respectively. solutions underscore imperative enhance efficiency economy shed light metabolic mechanisms. Furthermore, in order improve application potential -to-MCFAs, future priorities, e.g. exploitation functional pure bacteria, screening multi-omics analysis, genetic modification enhancement, enhancement bioreactor stability, specific MCFA development coupled purification economic benefits ecological environmental risks, prospected. This work is expected offer thorough understanding guide inspire researchers address critical in-depth propel
