The incorporation of radiolabelled tungsten ( 185 W) by a number of methanogens was, with the exception of Methanococcus vannielii, considerably higher during growth on H 2 /CO 2 than during growth on formate. Growth of Methanocorpusculum parvum on H 2 /CO 2 was positively affected by tungsten. Partially purified 63 Ni‐ or 185 W‐labelled cell extracts of Mcp. parvum revealed 63 Ni‐labelled F 430 and a 185 W‐labelled cell component. At present no physiological function of this latter compound is known.
