chemotrophs

Indeed, there are families of bacteria known as chemotrophs that derive their energy from various inorganic chemicals as opposed to sunlight (like plants) or organic nutrients (like us).

Through studying chemotrophs, we may be able to find ways to absorb energy directly from organic and inorganic material independently of the sun.

Departures from theoretical PQ and RQ and the possibility of nocturnal variations in formaldehyde and carbonate alkalinity imply that chemotrophs, both methane producers and methane oxidizers, play a significant role in CO2 cycling.

But they've likely only scratched the surface: Genome-mining has identified genes encoding LOV in 133 chemotrophs, while bioinformatics studies suggest that as many as 13\% of such bacteria have them.
