Abstract A vitamin B12-producing and hydrocarbon-utilizing bacterium, Corynebacterium simplex, accumulated an appreciable amount of cobalt-porphyrin in cultural filtrates when grown on a n-hexadecane medium containing sufficient amounts of cobaltous sulfate and an appropriate detergent. When grown without the detergent, the cobalt-porphyrin was found only in the cells of the organism. In the latter case, the content of cobalt-porphyrin was comparable to that of vitamin B12 and 7 times lower than that of iron-porphyrin. Though the organism required cobaltous sulfate for optimal growth, the requirement could be efficiently replaced by the supplementation of cobalt-porphyrin and partly of vitamin B12. The porphyrin moieties of extra- and intracellular cobalt-porphyrin were identified as coproporphyrin III in both cases.
