Although it is produced by both synthetic and fermentation processes, it is believed that the microbial synthesis should be able to compete quite successfully with the synthetic chemi

In this review, however, as in most publications, the word vitamin B. is given a very broad meaning so as to include all the cobalt corrinoids of the cobalamin group. Other cobalt corrinoids which can be considered analogous or precursors of cobalamins are also included.
