acetogens
Autotrophic bacteria that generate acetate as a product of anaerobic respiration. Typically they use hydrogen gas for energy and derive carbon for building organic molecules from inorganic carbon dioxide. Acetogens include certain types of endoliths found in igneous formations. In these basaltic rocks, the hydrogen is produced by the reaction of oxygen-poor water with iron-bearing minerals.
