Abstract

PURPOSE: To prepare the titled substance in high yield, by culturing microorganisms in a medium containing, as an effective nitrogen source, the cultured and hydrolyzed cells of bacteria belonging to Brevibacterium genus or Corynebacterium genus and capable of producing L-lysine.
CONSTITUTION: Cultured cells of bacteria capable of producing L-lysine and belonging to Brevibacterium genus or Corynebacterium genus, e.g. Brevibacterium lactofermentum FERM-P No.3840, Corynebacterium glutamicum FERM-P No.1982, etc., are hydrolyzed with a mineral acid, e.g. hydrochloric acid, sulfuric acid, etc., and the hydrolyzed product is added as an effective nitrogen source to a conventional nutrient medium at a concentration of 20W60mg/dl. Bacteria belonging to Brevibacterium genus or Corynebacterium genus and capable of producing L-glutamic acid are cultured in the medium obtained above, and L-glutamic acid is separated from the cultured medium by conventional means.
