L-lysine-producing strains ofwith enhanced lysE gene (lysine export carrier gene), in which strains additional genes chosen from the group comprising the dapA gene (dihydrodipicolinate synthase gene), the lysC gene (aspartate kinase gene), the dapB gene (dihydrodipicolinate reductase gene) and the pyc gene, but especially the dapA gene and the lysC gene (aspartate kinase gene), are enhanced and, in particular, over-expressed, and a process for the preparation of L-lysine.

L-lysine-producing corynebacteria and process for the preparation of L-lysine

The invention relates to L-lysine-producing strains of corynebacteria with enhanced lysE gene (lysine export carrier gene), in which strains additional genes chosen from the group comprising the dapA gene (dihydrodipicolinate synthase gene), the lysC gene (aspartate kinase gene), the dapB gene (dihydrodipicolinate reductase gene) and the pyc gene, but especially the dapA gene and the lysC gene (aspartate kinase gene), are enhanced and, in particular, over-expressed, and to a process for the preparation of L-lysine.
