    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(CO2)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CO2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CO2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CO2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CO2(scCO2)胁迫作用下,也会通过不同的适应性进化方式影响CO2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CO2影响条件下的scCO2-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CO2固定以及将其转化为高附加值产物的潜力。

    Abstract:

    Geological sequestration is the process that injects carbon dioxide (CO2) 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 CO2 permanently. Injecting massive amounts of CO2 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 CO2 will directly or indirectly affect the subsurface biogeochemical processes. When exposed to short-or long-term stresses by super-critical phase CO2(scCO2), adaptive evolution of the deep subsurface microorganisms may influence the fate and transport of the sequestered CO2. This review focuses on the latest progress in the domestic and international studies and the current understandings about the scCO2-water-microbe-mineral interactions in the subsurface environments impacted by CO2 geological sequestration. In addition, this paper also includes a discussion about the potential to enhance CO2 stabilization and transformation to the value-added products by the deep subsurface microorganisms.
