Clostridium magnum , originally described as a non‐autotrophic homoacetogenic bacterium, was found to be able to grow with H 2 /CO 2 , formate, or methanol with stoichiometric acetate formation, provided that the growth medium contained at least 0.025% (w/v) yeast extract. Hydrogen was also formed as a byproduct of glucose fermentation, and was consumed again after glucose consumption. Hydrogen formation from glucose was independent of growth conditions and reached similar maximal concentrations in mineral media with or without ammonia added as well as in non‐growing cultures or in the presence of carbon monoxide.
