Abstract
The corrinoids synthesized by the sulfate-reducing bacterium Desulfovi brio vulgaris were analyzed. The compounds found were guanylcobamide a nd hypoxanthylcobamide; structures were determined by mass spectrometr y, H-1-NMR, and ultraviolet/visible spectroscopy. D. vulgaris used ext ernally added guanine to form guanylcobamide, as demonstrated with 8-C -14-guanine. Addition of adenine did not lead to the formation of aden ylcobamide (pseudovitamin B-12), whereas 5,6-dimethylbenzimidazole was transformed into vitamin B-12.
