Since these bacteria obtain energy by the oxidation of electron donors (inorganic hydrogen sulfide) in their environments (chemical reactions) we can classify them as chemotrophs. In addition, they synthesize all necessary organic compounds from CO2 so they are autotrophs (opposite from heterotrophs that are unable to fix carbon).
