Abstract
L-Lysine is produced by cultivating mutant strains of Corynebacterium glutamicum that are derived from C. glutamicum ATCC 13287 or ATCC 14296, the mutant strains requiring leucine, histidine, or isoleucine and valine for growth in addition to the specific requirements of the parent organisms, which for ATCC 13287 are: homoserine or threonine and methionine or threonine and cystathionine or threonine and homocysteine and for ATCC 14296: threonine. The fermentation is conducted under aerobic conditions preferably at pH 5-8À5 and at 24-37 C. on a nutrient medium containing the necessary amino-acids which may be present as components of a natural substance such as a protein hydrolysate. Specified mutant strains of C. glutamicum are ATCC Nos. 21253, 21254, 21255, 21299 and 21300.
