Abstract

본 발명은 트립토판 분해요소 활성을 나타내지 않는 대장균 변이주의 돌연변이 처리에 의해 수득된 트립토판 분해효소 활성을 나타내는 대장균 역돌연변이주 및 그의 제조방법에 관한 것이다.The present invention relates to an E. coli reverse mutant strain exhibiting tryptophan lyase activity obtained by mutation treatment of E. coli mutant strains that do not exhibit tryptophan degrading element activity, and a method for producing the same.
