Subsurface carbon monoxide oxidation potentials revealed through genome-resolved metagenomics of a carboxydotroph. Subsurface carbon dioxide sequestration metagenome

Microbes play a key role in the biogeochemical cycling of carbon in the Earth's deep subsurface. This study is associated with a field-scale demonstration of supercritical CO2 geosequestration. Observed changes to the subsurface microbial community supports an important role in the aquifer microbiome for the thermophilic CO-utilizing anaerobe, Carboxydocella. Here, we employed genome-resolved metagenomics to reconstruct an aquifer-native Carboxydocella genome to near-complete.

微生物在地球深部地下环境的碳生物地球化学循环中发挥关键作用。本研究关联于超临界二氧化碳（supercritical CO₂）地质封存的现场规模示范项目。观测到的地下微生物群落变化证实，嗜热一氧化碳利用厌氧菌Carboxydocella在含水层微生物组中发挥着重要作用。本研究采用基因组解析宏基因组学技术，将一株含水层原生的Carboxydocella基因组组装至近完整状态。
