Since the growth inhibition of organisms of Lactobacteriaceae by OMP, BMP, and INAH was found to be specifically recovered by the pyridoxine group vitamins, their inhibition index was examined. With the same bacillus, recovery of inhibition was of the same order with pyridoxine, pyridoxal, and pyridoxamine, even if the inhibitor was different. The recovery became weaker in the order of pyridoxal, pyridoxamine, and pyridoxine for L. casei, and in the order of pyridoxamine, pyridoxal, and pyridoxine for St. faecalis and L. arabinosus, these orders being the same as their vitamin activity for these bacilli. The degree of growth inhibition by OMP against these bacilli is the same whether estimated by turbidity or by the amount of the acid formed. From these results, it is considered that OMP inhibits enzymes taking part in amino acid metabolism rather than the glycolytic enzyme system.
