Abundant and active acetogens enhance the carbon dioxide sink of Blue Carbon ecosystems
Collectively, these results reveal Blue Carbon ecosystems harbor microbial communities that can exclusively subsist by using CO<sub>2</sub> as their sole electron acceptor and carbon source. This provides evidence for a novel carbon sink pathway within these ecosystems beyond the well-known mechanisms of photosynthetic carbon fixation and soil sequestration. Additionally, the discovery and enrichment of these chemosynthetic communities provide opportunities for developing further mechanisms of CO<sub>2</sub> removal through industrial gas fermentation.
