Abstract The photolysis of deoxyadenosylcobalmin and methylcobalamin in water was studied. The results showed that the speed of photolytic cleavage is related to photolytic energy.The more photolytic energy ,the more photolytic speed. The content of hydroxycobalamin, which is the photolytic product of dexyadenosylcobalmin, is according to the contents of vitamin B12 in ferment broth. An new method measures the contents of vitamin B12 in fermentation broth is established.
