Cyanocobalamin is commercially prepared by [[bacterial fermentation]]. Fermentation by a variety of [[microorganism]]s yields a mixture of [[methylcobalamin]], [[hydroxocobalamin]] and [[adenosylcobalamin]]. These compounds are converted to cyanocobalamin by addition of [[potassium cyanide]] in the presence of [[sodium nitrite]] and heat. Since multiple species of ''[[Propionibacterium]]'' produce no [[exotoxin]]s or [[endotoxin]]s and have been granted [[GRAS]] status (generally regarded as safe) by the [[United States Food and Drug Administration]], they are the preferred bacterial fermentation organisms for vitamin {{chem|B|12}} production.</div>FuzzyBot
