Abstract
Preparation of L-ornithine by cultivating an auxotrophic mutant of bacteria of the family Enterobacteriaceae which requires citrulline or arginine for growth in an aqueous nutrient containing a source of carbon, a source of nitrogen and either citrulline or arginine. The preferred auxotrophs are those obtained from the species Escherichia coli, Aerobacter aerogenes, Proteus rettgeri and Proteus mirabilis. The arginine may be provided by the addition of peptane, meat extract, yeast extract, corn steep liquor or protein hydrolysate to the nutrient medium. The nutrient medium should preferably contain a source of phosphate ions.
