This study reveals the existence of active chemoautolithotrophic microbial communities in deep granitic groundwater, containing hydrogen and methane. Homoacetogens and acetotrophic methanogens dominated in the groundwater down to a depth of 112 m, while autotrophic methanogens prevailed deeper, down
