Area of Science:

• Microbiology
• Biotechnology
• Biochemistry

Background:

• Vitamin B12 is an essential nutrient crucial for various physiological processes.
• Methanol-utilizing bacteria are known producers of cobalamin (Vitamin B12).
• Optimization of microbial production is key to meeting the demand for Vitamin B12.

Purpose of the Study:

• To investigate and optimize the production of Vitamin B12 by a newly isolated methanol-utilizing bacterial strain.
• To determine the maximal yield achievable under optimized conditions.

Main Methods:
