In a gold mine, 2 miles under South Africa, Fort Saint Davids has determined that a strain of bacteria thriving in water trapped in a basalt rock has never used sunlight to live.

Other subterranean microbial communities are drawn to photosynthetic products if they do not directly use energy from the sun themselves.
