Cyanocobalamin is the stable form of Cobalamin which is not found in nature. Hundreds of fermentation processes and their modifications have been employed on commercial scale. In the first 24 hours, pH of fermentation is reduced due to rapid sugar consumption and again pH increases after 48 to 96 hours due to lysis of mycelium. A soluble cobalt salt is added to the fermentation reaction as a precursor to vitamin … 1. The culture of Streptomyces olivaceus is grown with aeration at 28°C in a nutritionally rich crude medium. Since the chemical synthesis of vitamin B12 involves a highly complicated, 70 step synthesis, vitamin Bi2 has been produced at industrial scale by fermentation using selective strain improvement by mutation followed by optimization of the fermentation process. ; When phosphate is added in the … ADVERTISEMENTS: The following points highlight the top two vitamins produced by microbial fermentation. Vitamin B12 biosynthesis is confined to few bacteria and archaea, and as such its production relies on microbial fermentation. In this review, however, as in most publications, the word vitamin B 12 is given a very broad meaning so as to include all the cobalt corrinoids of the cobalamin group. 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. Streptomyces olivaceus, Pseudomonas denitrificans, Propionibacterium shermanii and Propionibacterium freudenreichii are mainly used for commercial production of vitamin B12. 257-284).
