The present invention relates to (a) process for producing L-lysine by fermentation which comprises culturing a microorganism having resistance to 4-N-(D-alanyl)-2,4-diamino-2,4-dideoxy-L-arabinose 2,4-dideoxy-L-arabinose or a derivative thereof and belonging to the genus Brevibacterium or the genus Corynebacterium, (b) said bacterium therefore and (c) a method of producing said bacterium.

Process for producing L-lysine by fermentation

A process for producing L-lysine, which comprises culturing a mutant L-lysine-producing strain belonging to the genus Brevibacterium or the genus Corynebacterium and having selenalysine resistance in a nutrient medium, producing and accumulating L-lysine in the culture broth and collecting L-lysine from the culture broth.

Process for producing L-lysine by fermentation with a bacteria having

The present invention relates to a fermentation process using a L-lysine-producing microorganism having a resistance to an acyl-lysine, a methylated acyl-lysine or both an acyl-lysine and a methylated acyl-lysine. By the process of the present invention, L-lysine may be produced in high yields providing an improved process that reduces the cost of industrially produced L-lysine.
