摘　　要：微生物固定CO_(2)是一种极富前景的碳捕获和利用途径,对实现全球生态系统碳中和至关重要.非光合自养微生物由于其环境适应性强、固碳途径的多样性,以及会产生高附加值产物而备受关注.基于非光合自养微生物固定CO_(2)的研究进展,系统分析影响非光合自养微生物固碳效率的内部和外部因素,包括有固定CO_(2)途径、固碳关键酶、碳源、电子供体、代谢产物等,并列出多种增效策略.除了直接对应影响因素的增效方法外,还涉及微生物间的协同作用及代谢促进剂(生物炭与微纳米气泡)的使用.本工作有助于为深入理解和进一步增效非光合自养菌固定CO_(2)提供理论基础和技术支撑.Microbial CO_(2)xation is a promising pathway of carbon capture and utiliza-tion,which is crucial for achieving carbon neutrality in global ecosystems.Non-photosynthetic autotrophic microorganisms have attracted attention for their environmental adaptability,diversity of carbon xation pathways,and production of high value-added products.Based on domestic and foreign researchs on CO_(2)xation by non-photosynthetic autotrophic mi-croorganisms,we systematically analyzed internal and external factors affecting the carbon xation efficiency of non-photosynthetic autotrophic microorganisms,including CO_(2)xa-tion pathways,key carbon xing enzymes,carbon sources,electron donors,and metabo-lites.Various strategies for promoting microbial CO_(2)xation have been proposed.In addition to strategies involving direct responses to inuencing factors,strategies involv-ing synergy between microorganisms and the use of metabolic promoters(biochar and micro/nanobubbles)are also being investigated.This review provides a theoretical foun-dation and technical support for enhancing CO_(2)xation by non-photosynthetic autotrophic microorganisms.
