• 1. Two bacteria stems producing vitamin B6 were obtained. One is Klebsiella producing 2mg of pyridoxamine per liter in 60 hours and the other is Flavobacterium producing 4mg of pyridoxal per liter in 60 hours.2. Resting cell suspension of Flavobacterium was able to synthesize pyridoxal. Maximal synthesis was achieved in the presence of glycerol and an amino acid (aspartic acid or leucine).3. The carbon chains of both 14C-labeled glycerol and 14C-labeled leucine were efficiently incorporated into newly synthesized pyridoxal by the resting cell system. 14C-pyridoxal produced by cells incubated with 2-14C-aspartic acid was too low to permit a definitive conclusion.
