摘要: The invention relates to a bacterial process for producing phenylalanine. The process utilizes a Corynebacterium or Brevibacterium host which is transformed with a recombinant DNA. The recombinant DNA harbors a DNA containing a gene which encodes chorismate mutase or prephenate dehydratase. The transformed microorganism is then cultured in order to accumulate phenylalanine in the culture medium and the phenylalanine is recovered therefrom.
