The arginine catabolism of Thermanaerovibrio acidaminovorans was investigated. T. acidaminovorans was able to produce approximately 0.4–0.5 mol citrulline and 0.5–0.6 mol ornithine from 1 mol of arginine. However, in a methanogenic coculture with Methanobacterium thermoautotrophicum Z245 1 mol arginine was converted to approximately 1 mol of propionate, 0.5 mol acetate, 4 mol ammonia and 4 mol hydrogen; citrulline and ornithine were not formed. Enzyme measurements indicated the presence of the arginine deiminase pathway (ADI) in cells of T. acidaminovorans growing on arginine.
