Abstract

A process for producing L-lysine is disclosed in which a recombinant vector, a DNA fragment of which contains a gene involved in the synthesis of dihydropicolinic acid synthetase, is used to transform a microorganism of the genus Corynebacterium or Brevibacterium. The transformant is then cultured in a medium which supports the accumulation of L-lysine. Subsequently the L-lysine is recovered from the culture broth.
