S ummary . The yellow pigment excreted by a strain of Arthrobacter globiformis during exponential growth was identified as riboflav in. The amount produced was approximately 5 μ/mg of cells formed (dry weight) in all media tested, rich as well as poor. This value was also found in media containing 1% of Tween So, even though the concentration of internal flavins then was nearly one‐half the normal value. Over production of riboflavin in most media was 40‐50 fold. The specific growth rate of the riboflavin producer was sevral per cent less than that of a normal strain of the same species.
