   • Strain Culture Preparation: The selected strain is cultured and prepared in a nutrient-rich medium to create a starter culture. This culture is carefully monitored for purity and viability to ensure optimal fermentation.

2. Fermentation Process:

   • Fermentation Medium Preparation: The fermentation medium, containing essential nutrients like carbohydrates, nitrogen sources, and trace elements, is prepared and sterilized. The composition of the medium is optimized to promote B12 production.
   • Inoculation: The starter culture is introduced into the fermentation medium in large fermentation tanks under controlled conditions.
   • Controlled Conditions: The fermentation process is carefully controlled for temperature, pH, oxygen levels, and nutrient supply to maximize B12 production. These conditions are maintained throughout the fermentation period, which can last several days.

3. Extraction and Purification:

   • Cell Harvesting: After fermentation, the microbial cells are harvested from the fermentation broth.
   • Extraction: Vitamin B12 is extracted from the harvested cells using solvents or other extraction methods. The goal is to separate the B12 from the cellular material and fermentation residues.
   • Purification: The extracted B12 undergoes several purification steps to remove impurities. These steps may include filtration, chromatography, and crystallization to obtain a highly pure product.

4. Cyanation:

   • Conversion to Cyanocobalamin: The purified vitamin B12 is often converted to cyanocobalamin by adding cyanide. This step is done because cyanocobalamin is more stable and easier to handle than other forms of vitamin B12.
   • Quality Control: Rigorous quality control measures are implemented to ensure the final product meets purity and safety standards. This includes testing for contaminants, potency, and stability.

5. Drying and Packaging:
