Oxygen determines the requirement for cobalamin but not riboflavin in the growth of Propionibacterium freudenreichii

29 Jul 2025

Abstract excerpt

Vitamin B 12 (cobalamin, hereafter B 12 ) is essential for human health, particularly for neural function and DNA synthesis. It is synthesized exclusively by bacteria and archaea, with animal-derived foods serving as the primary sources for humans. Propionibacterium freudenreichii is notable for its long-standing use in food production, its efficient B 12 biosynthesis, and its minimal production of inactive...
