Streptomyces olivaceus, Pseudomonas denitrificans, Propionibacterium shermanii and Propionibacterium freudenreichii are mainly used for commercial production of vitamin B12. Vitamin B12 is produced industrially by microbial fermentation, using almost exclusively Pseudomonas denitrificans and Propionibacterium species (as reviewed by Spalla et al, 1989 “Microbial production of vitamin B12”, In: Biotechnology of vitamins, pigments and growth factors, E. J. Vandamme ed., Elsevier, London, N.Y., pp. The required amount of inoculum (5% of the volume of production medium) is prepared by successive transfers. Streptomyces griseus, a bacterium once thought to be a yeast, was the commercial source of vitamin B 12 for many years. ADVERTISEMENTS: The following points highlight the top two vitamins produced by microbial fermentation. Vitamin B12 activity that have been obtained from fermentation experiments of each microorganisms are determined by microbiological assays using Lactobacillus leichmannii IFO 3073 (ATCC 4797) which is a test microorganism. Vitamin B12 is a water-soluble vitamin, commonly known as cobalamin. As a result of these assays S. olivaceus IFO 3409 (2 micrograms/ml) was found as the most efficient strain were followed by S. olivaceus CBS 355.53 and S. griseus CBS 16.45 respectively. The culture of Streptomyces olivaceus is grown with aeration at 28°C in a nutritionally rich crude medium. For fermentation process Streptomyces griseus, Pseudomonas denitrificans, Streptomyces olivaceus and Propionibacterium shermaniiare used. Cyanocobalamin is the stable form of Cobalamin which is not found in nature. The cyanide (CN) group, hydroxyl group (- OH) or nitrite group (- NO2) attached to the cobalt is called cyanocobalamin (vitamin B12), hydroxocobalamin and nitritocobalamin respectively. The most commonly used microorganisms are — Propionibacterium freudenreichii, Pseudomonas denitrificans , Bacillus megaterium and Streptomyces olivaceus .

Commercial Production of Vitamin B 12: Vitamin B 12 is commercially produced by fermentation. Single step extraction into an organic solvent or counter-current extraction and product purification is carried out by the process of precipitation. Vitamin B12 is an essential micronutrient that is needed for functions such as maintaining the nervous system and forming blood cells. Hundreds of fermentation processes and their modifications have been employed on commercial scale. Some vitamins are already present in our body at the time of our birth but some need to be implanted externally and these vitamins are produced by microbial fermentation. Vitamin B12 is produced by bacteria and actinomycetes (Table 5.2). It could be concluded egy of betaine feeding for vitamin B12 fermentation, various ranges that the lower vitamin B12 production under 8–10 g/l of betaine of betaine concentrations were controlled by betaine feeding in was possibly due to more severe cell growth inhibition by this 120-m3 fermenter, and Fig. The medium is filtered to remove mycelium and then the filtrate broth is treated with cyanide to convert cobalamin to cyanocobalamin. 2008 Jun;24(6):927-32.
