Superiority
Vitamin B12 is the latest found in B vitamins to date. Vitamin B12 is a polycyclic compound containing trivalent cobalt, and the four reduced pyrrole rings are joined together to form one porphyrin macrocycle (similar to porphyrin), which is the core of vitamin B12 molecule. Therefore, compounds containing such a ring are referred to as porphyrins.
The main physiological function of vitamin B12 is to participate in the production of bone marrow red blood cells to prevent pernicious anemia; to prevent damage to brain nerves.
The industrial manufacture of vitamin B12 is made by microbial fermentation.
Streptomyces griseus has been a source of vitamin B12 for many years. Usually from Pseudomonas denitrificans and Propionibacterium shermanii. They generally need to be cultured under special conditions to increase the yield.
