Microbial synthesis of riboflavin and the intra and extrabacterial distribution of the vitamin were studied with typical bacteria found in human intestinal tracts, with culture in bouillon medium at 37℃ for 24 hours. The results obtained showed that the highest amount of riboflavin was produced by Alcaligenes faecclis of all intestinal bacteria tested, the ratio of extrabacterial riboflavin to intrabacterial one was highest in Escherichia coli communior, and almost all of riboflavin in the bacterial cell was FAD, while free riboflavin was abundant in the medium.

In order to determine how much intestinal bacteria synthesize riboflavin during growth, the riboflavin contents of intra- and extrabacterial body, the ratio of both contents and the forms of riboflavin were studied. The measurement was carried out in shaking cultures of E. coli communis grown in Anderson's medium for 6,12,18,24,30,and 36 hours. The riboflavin content within the bacterial body increased to a maximum at 18 hours. Later, it decreased. The riboflavin value found in extrabacterial body per nitrogen indicated maximum figures at 18-24 hours. Then, it decreased slowly. The riboflavin contained in the medium per ml reached a maximum at this stage and scarcely increased ever since. The ratio of both contents (extrabacterial body/intrabacterial body) reached a minimum at 18 hours.

It has been reported that human feces destructs riboflavin. This paper deals with the decomposition of riboflavin by feces of twelve species of animals. The results obtained suggest that the ability of excrements for destructing riboflavin seems to be different with the species of animals, the kinds of diets and the digestive ability of animals.
