The oxyhydrogen reaction of the cyanobacterium Anabaena cylindrica was shown to be dependent on the availability of nickel ions in the growth medium. The rate of nitrogenase‐catalyzed hydrogen formation was shown to be inversely related to the capacity of the cells to consume hydrogen gas as seen by experiments in which the nickel ion concentration was systematically varied. Nickel‐depleted cultures released hydrogen in air and dinitrogen.
