Rar, aber relevant: die seltene Biosphäre im Hoch-CO2-Untergrund Egergraben

Abstract Understanding microbial behavior in high CO 2 subsurface systems is pivotal for CO 2 capture and mitigation and achieving long-term climate goals. Genomic analysis of sediments and enrichment cultures from the geologically active Eger Rift region emphasize the significance of the rare biosphere in such efforts. Despite being scarce in the native community, sulfate-reducing and methanogenic taxa became active under high CO 2 and H 2 conditions, highlighting their metabolic role in subsurface environments.
