Claims (3)

  1. 고정화 효소원을 사용하여 인돌 및 L-세린을 반응시켜 L-트립토판을 연속적으로 제조하는 방법에 있어서, 반응 혼합물중의 L-세린의 몰랄수를 인돌 및 L-트립토판의 총몰랄수 보다도 과잉으로 존재케하는 것을 특징으로 하는 L-트립토판의 연속 제조방법.
  2. 제1항에 있어서, L-세린의 몰랄수를 인돌 및 L-트립토판의 몰랄수의 합에 대해서는 1.2배 이상으로 하고, 인돌의 몰랄수에 대해서는 1.5배 이상으로 하는 것을 특징으로 하는 방법.
  3. 제1항에 있어서, 상기 반응이 다수의 반응기내에서 실시되며, 제1항의 반응조건은 각 반응기를 충족시키며, 이전의 반응기로부터 유출된 반응 생성물은 두 번째 및 다음의 반응기에 첨가되며, 필요하다면, 제1항의 조건을 만족시키기 위하여, L-세린을 반응기에 첨가시키는 것을 특징으로 하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
