摘要
A process for the preparation of L-lysine in which recombinant DNA which consists of a DNA fragment which has a genetic sequence coding for the production of proteins which lead to an aspartyl- beta -semialdehyde dehydrogenase (asd) activity or to the deregulation of aspartate kinase (lysC), which sequence derives from a microorganism of the genus Corynebacterium or Brevibacterium, and of vector DNA is inserted into a microorganism of the genus Corynebacterium or Brevibacterium, the transformants obtained in this way are cultured in a suitable medium, and the L-lysine which is produced is separated therefrom, is described.
