Using metagenomic sequencing, researchers reconstructed genomes from uncultivated microorganisms and identified novel pathways for carbon fixation and energy metabolism. The findings expand current understanding of Earth's deep biosphere and the ecological roles of microorganisms living in nutrient-limited underground environments.","tags":["deep biosphere","microbial dark matter","carbon fixation","subsurface microbiology","groundwater","metagenomics","extremophiles"],"priceUSDC":"0.0001"}
