UN PROCEDIMIENTO PARA PRODUCIR L-ISOLEUCINA

摘要

Disclosed is a process for producing L-isoleucine by transforming a host microorganims belonging to the genus Corynebacterium or Brevibacterium with a recombinant DNA of a DNA fragment containing a gene encoding for the enzyme involved in the biosynthesis of threonine from aspartic acid and a vector DNA, culturing the transformant in a nutrient medium, accumulating L-isoleucine in the culture medium and recovering L-isoleucine therefrom.
