ABSTRACT:
The present invention provides a process for producing substances such as L-tryptophan and L-threonine, which comprises transforming a serine-requiring microorganism belonging to the genus Corynebacterium or Brevibacterium by incorporation of a recombinant plasmid containing a gene which complements the serine-requirement of the host and a gene which relates to the biosynthesis of a desired substance; culturing the obtained transformant in a culture medium; allowing the substance produced by the transformant to accumulate in the culture; and recovering the substance from the culture.
