Abstract: Microbial CO2 fixation is a promising pathway of carbon capture and utilization, which is crucial for achieving carbon neutrality in global ecosystems. Non-photosynthetic autotrophic microorganisms have attracted attention for their environmental adaptability, diversity of carbon fixation pathways, and production of high value-added products. Based on domestic and foreign researchs on CO2 fixation by non-photosynthetic autotrophic microorganisms, we systematically analyzed internal and external factors affecting the carbon fixation efficiency of non-photosynthetic autotrophic microorganisms, including CO2 fixation pathways, key carbon fixing enzymes, carbon sources, electron donors, and metabolites. Various strategies for promoting microbial CO2 fixation have been proposed. In addition to strategies involving direct responses to influencing factors, strategies involving synergy between microorganisms and the use of metabolic promoters (biochar and micro/nanobubbles) are also being investigated. This review provides a theoretical foundation and technical support for enhancing CO2 fixation by non-photosynthetic autotrophic microorganisms.

Key words: non-photosynthetic autotrophic microorganisms, CO2 fixation, electron donors, microbial synergy, metabolic promoters
