The “amino acid oxidase activity” for reaction 1 means an activity catalyzing the reaction shown in scheme (13). Generally, L-amino acid oxidase generates keto acid from the corresponding L-amino acid, while D-amino acid oxidase generates keto acid from the corresponding D-amino acid. Specifically, in accordance with the present invention, individually, a microorganism having L-amino acid oxidase activity may be used when L-tryptophan is used as the raw material, while a microorganism having D-amino acid oxidase activity may used when D-tryptophan is used as the raw material. Additionally, the preparation from DL-tryptophan is also applicable. When D- and L-amino acid oxidase is allowed to interact with DL-tryptophan, the intended indole-3-pyruvic acid may be quantitatively produced. When D- or L-amino acid oxidase interacts with DL-tryptophan, otherwise, the intended indole-3-pyruvic acid may be produced at a yield of 50%.
