Dissolved inorganic carbon supports robust anabolism and methanogenesis in actively serpentinizing rocks
Serpentinites, hydrated ultramafic rocks that produce [hyper]alkaline, reducing, H2-rich groundwaters, host subsurface microbial ecosystems. Though in the presence of enormous reducing power, life in ...
