Vitamin B₁₂ sources and microbial interaction.

ABSTRACT: Vitamin B₁₂ is synthesized only by certain bacteria and archaeon, but not by plants. The synthesized vitamin B₁₂ is transferred and accumulates in animal tissues, which can occur in certain plant and mushroom species through microbial interaction. In particular, the meat and milk of herbivorous ruminant animals (e.g. cattle and sheep) are good sources of vitamin B₁₂ for humans. Ruminants acquire vitamin B₁₂, which is considered an essential nutrient, through a symbiotic relationship with the bacteria present in their stomachs. In aquatic environments, most phytoplankton acquire vitamin B₁₂ through a symbiotic relationship with bacteria, and they become food for larval fish and bivalves. Edible plants and mushrooms rarely contain a cons
