A new species Corynebacterium glycinophilum nov. sp. was isolated from a putrefied banana, which is resistant to a high concentration of glycine and has a prominent ability of producing L-serine from glycine.
Among various substances supplemented to the medium used, nicotinamide was found to be effective for L-serine production. The L-serine production was in parallel with the consumption of glycine in the medium. Ferrous ion was found to depress L-serine production and to increase the assimilation of glycine added.
Glycine was utilized as a nitrogen source in the presence of glucose, but was not utilized as a carbon source in the absence of glucose. The addition of inorganic nitrogen increased L-serine production. Glycine was not formed from L- serine. L-Threonine was formed with L-serine from glycine, probably by serine transhydroxymethylase.
