Abstract
A process for producting vitamin B.sub.6 comprises cultivating a microorganism belonging to the genus Rhizobium and being capable of producing vitamin B.sub.6 in a culture medium under aerobic conditions, and separating the resulting vitamin B.sub.6 from the fermentation broth. As well as containing assimilable carbon sources, digestible nitrogen sources, inorganic salts and other nutrients necessary for the growth of the microorganism, the culture medium preferably additionally contains pyruvate, D-glyceraldehyde, glycolaldehyde, glycine, 1-deoxy-D-threo-pentulose, 4-hydroxy-L-threonine or a mixture thereof. This process affords high yields of vitamin B.sub.6, a vitamin essential for the nutrition of animals, plants and microorganisms and useful as a medicine and in foodstuffs.
