Abstract

PURPOSE: To obtain L-tryptophan important for essential amino acids from an industrally available inexpensive material, by using an enzyme system produced by specific microorganisms.
CONSTITUTION: Strains of microorganisms, e.g. Proteus vulgaris IFO3167, Escherichia coli IAM1268, or Aerobacter aerogenes IFO12019, which belong to the genuses Proteus, Escherichia, Aerobacter, Klebsiella or Bacillus, and have the ability to produce the L-tryptophan from indole, glycidic acid, and ammonia, are cultured in an L-tryptophan-containing nutrient medium. Indole, glycidic acid, and ammonia are subjected to the action of the culture thus obtained and live bacterium bodies which may be treated, to give L-tryptophan.
