摘　　要：地质封存将工业和能源相关领域生产活动产生的二氧化碳(CO_(2))进行捕集并注入到深部地下岩石构造中,以实现长期储存的目标,是降低温室气体排放、实现CO_(2)长期封存的重要可行性手段之一。向深部地下地质构造中注入大量CO_(2)会导致深地环境发生显著变化,进而引起原生微生物活性及群落结构发生明显改变。因此,地质封存CO_(2)能够直接或间接影响深地微生物驱动的生物地球化学过程。同时,微生物在短期和长期的超临界CO_(2)(scCO_(2))胁迫作用下,也会通过不同的适应性进化方式影响CO_(2)在地下环境中的迁移、转化和赋存形态。本文介绍了国内外二氧化碳捕获与封存发展现状以及地质封存CO_(2)影响条件下的scCO_(2)-水-微生物-矿物的相互作用领域的最新科研进展,并展望了利用深地微生物强化CO_(2)固定以及将其转化为高附加值产物的潜力。Geological sequestration is the process that injects carbon dioxide(CO_(2))captured from an industrial or energy-related source into deep subsurface rock formations for long-term storage,which is one of the viable and feasible means to reduce greenhouse gas emission and sequester CO_(2)permanently.Injecting massive amounts of CO_(2)into the deep geological formations may cause significant changes to subsurface that abundant microbiota use as habitats,and hence influence microbial activity and microbial structure.Thus,geological sequestration of CO_(2)will directly or indirectly affect the subsurface biogeochemical processes.When exposed to short-or long-term stresses by super-critical phase CO_(2)(scCO_(2)),adaptive evolution of the deep subsurface microorganisms may influence the fate and transport of the sequestered CO_(2).This review focuses on the latest progress in the domestic and international studies and the current understandings about the scCO_(2)-water-microbe-mineral interactions in the subsurface environments impacted by CO_(2)geological sequestration.In addition,this paper also includes a discussion about the potential to enhance CO_(2)stabilization and transformation to the value-added products by the deep subsurface microorganisms.
